1. Unified Framework for Matchgate Classical Shadows

Author

Subjects
Quantum Physics
Abstract

Estimating quantum fermionic properties is a computationally difficult yet crucial task for the study of electronic systems. Recent developments have begun to address this challenge by introducing classical shadows protocols relying on sampling of Fermionic Gaussian Unitaries (FGUs): a class of transformations in fermionic space which can be conveniently mapped to matchgates circuits. The different protocols proposed in the literature use different sub-ensembles of the orthogonal group $O(2n)$ to which FGUs can be associated. We propose an approach that unifies these different protocols, proving their equivalence, and deriving from it an optimal sampling scheme. We begin by demonstrating that the first three moments of the FGU ensemble associated with $SO(2n)$ and of its intersection with the Clifford group are equal, generalizing a result known for $O(2n)$ and addressing a question raised in previous works. Building on this proof, we establish the equivalence between the shadows protocols resulting from FGU ensembles analyzed in the literature. Finally, from our results, we propose a sampling scheme for a small sub-ensemble of matchgates circuits that is optimal in terms of number of gates and that inherits the performances guarantees of the previous ensembles., Comment: 20 pages, 5 figures

Abstract

Parameterized quantum circuits used as variational ans\"atze are emerging as promising tools to tackle complex problems ranging from quantum chemistry to combinatorial optimization. These variational quantum circuits can suffer from the well-known curse of barren plateaus, which is characterized by an exponential vanishing of the cost-function gradient with the system size, making training unfeasible for practical applications. Since a generic quantum circuit cannot be simulated efficiently, the determination of its trainability is an important problem. Here we find an efficient method to compute the gradient of the cost function and its variance for a wide class of variational quantum circuits. Our scheme relies on our proof of an exact mapping from randomly initialized circuits to a set of Clifford circuits that can be efficiently simulated on a classical computer by virtue of the celebrated Gottesmann-Knill theorem. This method is scalable and can be used to certify trainability for variational quantum circuits and explore design strategies that can overcome the barren plateau problem. As illustrative examples, we show results with up to 100 qubits., Comment: Revised version with three additional figures and results with up to 100 qubits

3. Machine learning via relativity-inspired quantum dynamics

Abstract

We present a machine-learning scheme based on the relativistic dynamics of a quantum system, namely a quantum detector inside a cavity resonator. An equivalent analog model can be realized for example in a circuit QED platform subject to properly modulated driving fields. We consider a reservoir-computing scheme where the input data are embedded in the modulation of the system (equivalent to the acceleration of the relativistic object) and the output data are obtained by linear combinations of measured observables. As an illustrative example, we have simulated such a relativistic quantum machine for a challenging classification task, showing a very large enhancement of the accuracy in the relativistic regime. Using kernel-machine theory, we show that in the relativistic regime the task-independent expressivity is dramatically magnified with respect to the Newtonian regime., Comment: Article (2 figures) + Suppl.

4. Noisy Quantum Kernel Machines

Abstract

In the noisy intermediate-scale quantum era, an important goal is the conception of implementable algorithms that exploit the rich dynamics of quantum systems and the high dimensionality of the underlying Hilbert spaces to perform tasks while prescinding from noise-proof physical systems. An emerging class of quantum learning machines is that based on the paradigm of quantum kernels. Here, we study how dissipation and decoherence affect their performance. We address this issue by investigating the expressivity and the generalization capacity of these models within the framework of kernel theory. We introduce and study the effective kernel rank, a figure of merit that quantifies the number of independent features a noisy quantum kernel is able to extract from input data. Moreover, we derive an upper bound on the generalization error of the model that involves the average purity of the encoded states. Thereby we show that decoherence and dissipation can be seen as an implicit regularization for the quantum kernel machines. As an illustrative example, we report exact finite-size simulations of machines based on chains of driven-dissipative quantum spins to perform a classification task, where the input data are encoded into the driving fields and the quantum physical system is fixed. We determine how the performance of noisy kernel machines scales with the number of nodes (chain sites) as a function of decoherence and examine the effect of imperfect measurements., Comment: 18 pages, 9 figures

Abstract

Biomaterials that can improve the healing of articular cartilage lesions are needed. To address this unmet need, we developed novel 3D printed silica/poly(tetrahydrofuran)/poly(ε-caprolactone) (SiO2/PTHF/PCL-diCOOH) hybrid scaffolds. Our aim was to carry out essential studies to advance this medical device towards functional validation in pre-clinical trials. First, we show that the chemical composition, microarchitecture and mechanical properties of these scaffolds were not affected by sterilisation with gamma irradiation. To evaluate the systemic and local immunogenic reactivity of the sterilised 3D printed hybrid scaffolds, they were implanted subcutaneously into Balb/c mice. The scaffolds did not trigger a systemic inflammatory response over one week of implantation. The interaction between the host immune system and the implanted scaffold elicited a local physiological reaction with infiltration of mononuclear cells without any signs of a chronic inflammatory response.Then, we investigated how these 3D printed hybrid scaffolds direct chondrogenesis in vitro. Human bone marrow-derived mesenchymal stem/stromal cells (hBM-MSCs) seeded within the 3D printed hybrid scaffolds were cultured under normoxic or hypoxic conditions, with or without chondrogenic supplements. Chondrogenic differentiation assessed by both gene expression and protein production analyses showed that 3D printed hybrid scaffolds support hBM-MSC chondrogenesis. Articular cartilage-specific extracellular matrix deposition within these scaffolds was enhanced under hypoxic conditions (1.7 or 3.7 fold increase in the median of aggrecan production in basal or chondrogenic differentiation media).Our findings show that 3D printed SiO2/PTHF/PCL-diCOOH hybrid scaffolds have the potential to support the regeneration of cartilage tissue.

Abstract

Introduction: Hybrids consist of inorganic and organic co-networks that are indistinguishable above the nanoscale, which can lead to unprecedented combinations of properties, such as high toughness and controlled degradation.Methods: We present 3D printed bioactive hybrid scaffolds for bone regeneration, produced by incorporating calcium into our “Bouncy Bioglass”, using calcium methoxyethoxide (CME) as the calcium precursor. SiO2-CaOCME/PTHF/PCL-diCOOH hybrid “inks” for additive manufacturing (Direct Ink Writing) were optimised for synergy of mechanical properties and open interconnected pore channels.Results and Discussion: Adding calcium improved printability. Changing calcium content (5, 10, 20, 30, and 40 mol.%) of the SiO2-CaOCME/PTHF/PCL-diCOOH hybrids affected printability and mechanical properties of the lattice-like scaffolds. Hybrids containing 30 mol.% calcium in the inorganic network (70S30CCME-CL) printed with 500 µm channels and 100 µm strut size achieved the highest strength (0.90 ± 0.23 MPa) and modulus of toughness (0.22 ± 0.04 MPa). These values were higher than Ca-free SiO2/PTHF/PCL-diCOOH hybrids (0.36 ± 0.14 MPa strength and 0.06 ± 0.01 MPa toughness modulus). Over a period of 90 days of immersion in simulated body fluid (SBF), the 70S30CCME-CL hybrids also kept a stable strain to failure (~30 %) and formed hydroxycarbonate apatite within three days. The extracts released by the 70S30CCME-CL hybrids in growth medium did not cause cytotoxic effects on human bone marrow stromal cells over 24 h of culture.

Abstract

This study evaluated the use of silica/poly(tetrahydrofuran)/poly(ε-caprolactone) (SiO2/PTHF/PCL-diCOOH) 3D-printed scaffolds, with channel sizes of either 200 (SC-200) or 500 (SC-500) µm, as biomaterials to support the chondrogenesis of sheep bone marrow stem cells (oBMSC), under in vitro conditions. The objective was to validate the potential use of SiO2/PTHF/PCL-diCOOH for prospective in vivo ovine studies. The behaviour of oBMSC, with and without the use of exogenous growth factors, on SiO2/PTHF/PCL-diCOOH scaffolds was investigated by analysing cell attachment, viability, proliferation, morphology, expression of chondrogenic genes (RT-qPCR), deposition of aggrecan, collagen II, and collagen I (immunohistochemistry), and quantification of sulphated glycosaminoglycans (GAGs). The results showed that all the scaffolds supported cell attachment and proliferation with upregulation of chondrogenic markers and the deposition of a cartilage extracellular matrix (collagen II and aggrecan). Notably, SC-200 showed superior performance in terms of cartilage gene expression. These findings demonstrated that SiO2/PTHF/PCL-diCOOH with 200 µm pore size are optimal for promoting chondrogenic differentiation of oBMSC, even without the use of growth factors.

Abstract

The current study examines the desiccation-resistant Ramlibacter tataouinensis TTB310T as a model organism for the production of novel exopolysaccharides and their structural features. This bacterium is able to produce dividing forms of cysts which synthesize cell-bound exopolysaccharide. Initial experiments were conducted on the enrichment of cyst biomass for exopolysaccharide production under batch-fed conditions in a pilot-scale bioreactor, with lactate as the source of carbon and energy. The optimized medium produced significant quantities of exopolysaccharide in a single growth phase, since the production of exopolysaccharide took place during the division of the cysts. The exopolysaccharide layer was extracted from the cysts using a modified trichloroacetic acid method. The biochemical characterization of purified exopolysaccharide was performed by gas chromatography, ultrahigh-resolution mass spectrometry, nuclear magnetic resonance, and Fourier-transform infrared spectrometry. The repeating unit of exopolysaccharide was a decasaccharide consisting of ribose, glucose, rhamnose, galactose, mannose, and glucuronic acid with the ratio 3:2:2:1:1:1, and additional substituents such as acetyl, succinyl, and methyl moieties were also observed as a part of the exopolysaccharide structure. This study contributes to a fundamental understanding of the novel structural features of exopolysaccharide from a dividing form of cysts, and, further, results can be used to study its rheological properties for various industrial applications.

21. Experimental Tests for Measuring Individual Attentional Characteristics in Songbirds

Abstract

Attention is defined as the ability to process selectively one aspect of the environment over others and is at the core of all cognitive processes such as learning, memorization, and categorization. Thus, evaluating and comparing attentional characteristics between individuals and according to situations is an important aspect of cognitive studies. Recent studies showed the interest of analyzing spontaneous attention in standardized situations, but data are still scarce, especially for songbirds. The present study adapted three tests of attention (towards visual non-social, visual social, and auditory stimuli) as tools for future comparative research in the European starling (Sturnus vulgaris), a species that is well known to present individual variations in social learning or engagement. Our results reveal that attentional characteristics (glances versus gazes) vary according to the stimulus broadcasted: more gazes towards unusual visual stimuli and species-specific auditory stimuli and more glances towards species-specific visual stimuli and hetero-specific auditory stimuli. This study revealing individual variations shows that these tests constitute a very useful and easy-to-use tool for evaluating spontaneous individual attentional characteristics and their modulation by a variety of factors. Our results also indicate that attentional skills are not a uniform concept and depend upon the modality and the stimulus type.

Abstract

Small interfering RNAs (siRNAs) are promising molecules for developing new therapies based on gene silencing; however, their delivery into cells remains an issue. In this study, we took advantage of stapled peptide technology that has emerged as a valuable strategy to render natural peptides more structured, resistant to protease degradation and more bioavailable, to develop short carriers for siRNA delivery. From the pool of stapled peptides that we have designed and synthesized, we identified non-toxic vectors that were able to efficiently encapsulate siRNA, transport them into the cell and induce gene silencing. Remarkably, the most efficient stapled peptide (JMV6582), is composed of only eight amino-acids and contains only two cationic charges.

Abstract

Regenerative medicine solutions require thoughtful design to elicit the intended biological response. This includes the biomechanical stimulus to generate an appropriate strain in the scaffold and surrounding tissue to drive cell lineage to the desired tissue. To provide appropriate strain on a local level, new generations of scaffolds often involve anisotropic spatially graded mechanical properties that cannot be characterised with traditional materials testing equipment. Volumetric examination is possible with three-dimensional (3D) imaging, in situ loading and digital volume correlation (DVC). Micro-CT and DVC were utilised in this study on two sizes of 3D-printed inorganic/organic hybrid scaffolds (n = 2 and n = 4) with a repeating homogenous structure intended for cartilage regeneration. Deformation was observed with a spatial resolution of under 200 µm whilst maintaining displacement random errors of 0.97 µm, strain systematic errors of 0.17% and strain random errors of 0.031%. Digital image correlation (DIC) provided an analysis of the external surfaces whilst DVC enabled localised strain concentrations to be examined throughout the full 3D volume. Strain values derived using DVC correlated well against manually calculated ground-truth measurements (R2 = 0.98, n = 8). The technique ensures the full 3D micro-mechanical environment experienced by cells is intimately considered, enabling future studies to further examine scaffold designs for regenerative medicine.

Abstract

Osteochondral injuries are increasingly prevalent, yet success in articular cartilage regeneration remains elusive, necessitating the development of new surgical interventions and novel medical devices. As part of device development, animal models are an important milestone in illustrating functionality of novel implants. Inspection of the tissue-biomaterial system is vital to understand and predict load-sharing capacity, fixation mechanics and micromotion, none of which are directly captured by traditional post-mortem techniques. This study aims to characterize the localised mechanics of an ex vivo ovine osteochondral tissue–biomaterial system extracted following six weeks in vivo testing, utilising laboratory micro-computed tomography, in situ loading and digital volume correlation. Herein, the full-field displacement and strain distributions were visualised across the interface of the system components, including newly formed tissue. The results from this exploratory study suggest that implant micromotion in respect to the surrounding tissue could be visualised in 3D across multiple loading steps. The methodology provides a non-destructive means to assess device performance holistically, informing device design to improve osteochondral regeneration strategies.

34. Tempering Feydeau: Twisting and Guilty Pleasures on the London Stage (1893-1897)

Abstract

Beginning in 1892, Feydeau established himself in France as the new master of vaudeville comedy. London theatres surrendered to his infectious laughter, producing a number of his plays between 1892 and 1897, though admittedly, carefully selected: The Sportsman, adapted from Monsieur chasse! , The Other Man from Champignol malgré lui, His Little Dodge (Le Système Ribadier), A Night Out (L’Hôtel du Libre-Échange) and A Night Session (Séance de nuit). By reviewing the manuscripts submitted to the Office of the Lord Chamberlain, our article proposes to examine the approaches that made it possible for London directors and producers to edit light comedies which, with the name Feydeau, boasted of their French origin and frivolous nature, even when this choice carried inevitable risks. How could they avoid offending a Lord Chamberlain, hostile to any signs of immorality, with these plays, which were often based on subversive and ribald comedy? In each case, the manuscripts submitted for his censorship, in the proposed texts, reveal a prior self-censorship, evident both in the choices of the plays presented, and in the contortions of the adapters and translators: transpositions of situations, cuts and line changes all aimed at smoothing over or toning down the comedic effects relating to sexuality, as well as to social divisions. Even the most faithful translations brought about a shift in the starting situation, profoundly changing Feydeau’s reflections on intimate relationships and social ties. But why edit these plays, and deliberately run into such obstacles? Perhaps the dramatic and rhythmic inventiveness of Feydeau’s plays was an irresistible attraction to both performers and the public, as the study of their reception reveals. Even when adapters were often compelled to reduce Feydeau’s text, they also easily found the means to introduce clownish acts that were likely to please British audiences.

37. Machine learning via relativity-inspired quantum dynamics

Abstract

We present a machine-learning scheme based on the relativistic dynamics of a quantum system, namely a quantum detector inside a cavity resonator. An equivalent analog model can be realized for example in a circuit QED platform subject to properly modulated driving fields. We consider a reservoir-computing scheme where the input data are embedded in the modulation of the system (equivalent to the acceleration of the relativistic object) and the output data are obtained by linear combinations of measured observables. As an illustrative example, we have simulated such a relativistic quantum machine for a challenging classification task, showing a very large enhancement of the accuracy in the relativistic regime. Using kernel-machine theory, we show that in the relativistic regime the task-independent expressivity is dramatically magnified with respect to the Newtonian regime., Article (2 figures) + Suppl.

Abstract

In the noisy intermediate-scale quantum era, an important goal is the conception of implementable algorithms that exploit the rich dynamics of quantum systems and the high dimensionality of the underlying Hilbert spaces to perform tasks while prescinding from noise-proof physical systems. An emerging class of quantum learning machines is that based on the paradigm of quantum kernels. Here, we study how dissipation and decoherence affect their performance. We address this issue by investigating the expressivity and the generalization capacity of these models within the framework of kernel theory. We introduce and study the effective kernel rank, a figure of merit that quantifies the number of independent features a noisy quantum kernel is able to extract from input data. Moreover, we derive an upper bound on the generalization error of the model that involves the average purity of the encoded states. Thereby we show that decoherence and dissipation can be seen as an implicit regularization for the quantum kernel machines. As an illustrative example, we report exact finite-size simulations of machines based on chains of driven-dissipative quantum spins to perform a classification task, where the input data are encoded into the driving fields and the quantum physical system is fixed. We determine how the performance of noisy kernel machines scales with the number of nodes (chain sites) as a function of decoherence and examine the effect of imperfect measurements., 18 pages, 9 figures

41. Revoir le symbolisme pictural : le cas de Gustave Moreau : thème du féminin, style, réception critique

Abstract

Symbolism is generally seen as a literary movement, unified by the theme of the feminine. However, painting occupies an important place in the symbolism construction and the theme of the feminine cannot be the only way to question this movement. This thesis proposes to question the dominant assumptions about this movement: the anteriority of literary symbolism over pictorial symbolism, the importance of the feminine theme in painting, the lack or even the absence of stylistic studies. The Symbolist corpus being vast, the painter Gustave Moreau is raised as an archetype of pictorial symbolism and is posed as the privileged case of this study. The thematic, stylistic, and quantitative studies of Gustave Moreau’s pictorial works allow to immediately qualify this supposed anteriority of literature, by showing that pictorial productions historically precede literary productions by three decades. From this singular corpus of paintings, the theme of the feminine is thus re-examined: is this theme dominant in Gustave Moreau's production? Once again, the idea according to which theme of the feminine founded Symbolism is challenged by the quantitative studies made on this corpus. If the theme of the feminine no longer appears fundamental, then the question of style arises. The stylistic study of Gustave Moreau’s work shows an innovative and singular painter, who will nevertheless be erased - like artworks in general - in the critical historiography of the movement. The analysis of the critical reception and historiography of Symbolism thus shows how artists, artworks and stylistics have been marginalized in favor of literary, poetic, and philosophical thought of Symbolism., Le symbolisme est généralement considéré comme un mouvement littéraire, unifié par le thème du féminin. Or, la peinture occupe elle aussi une place importante dans la constitution du symbolisme et le thème du féminin ne saurait être l’entrée unique pour appréhender ce mouvement. Cette thèse se propose d’interroger les présupposés dominants sur ce mouvement : l’antériorité du symbolisme littéraire sur le symbolisme pictural, l’importance du thème du féminin dans la peinture, le manque voire l’absence des études stylistiques. Le corpus symboliste étant vaste, le peintre Gustave Moreau est érigé en archétype du symbolisme pictural et se pose comme le cas privilégié de cette étude. Les œuvres picturales replacées ici au centre des analyses thématiques, stylistiques et quantitatives, permettent de nuancer d’emblée cette supposée antériorité de la littérature, en montrant que les productions picturales précèdent historiquement d’une triple décennie les productions littéraires. À partir de ce corpus pictural singulier, le thème du féminin est ainsi réinterrogé : ce thème est-il si important dans la production de Gustave Moreau ? Les analyses quantitatives auxquelles est soumis le corpus permettent là encore de nuancer l’idée selon laquelle ce thème serait fondateur dans le symbolisme. Si le thème n’apparaît plus fondamental, la question du style s’impose alors. L’étude stylistique de l’œuvre de Gustave Moreau montre un peintre innovant et singulier, qui sera pourtant effacé – à l’instar des œuvres de manière générale – dans l’historiographie critique du mouvement. L’analyse de la réception critique et de l’historiographie du symbolisme montre ainsi comment les artistes, les œuvres et la stylistique ont été marginalisés au profit d’une pensée littéraire, poétique et philosophique du symbolisme.

Abstract

Nous nous proposons d’analyser Livro de Pré-Coisas d’un point de vue écocritique (en étudiant le rapport entre l’humain et la nature). Nous verrons que la relation avec la nature tient du véritable corps à corps : les métamorphoses des corps, mais également des éléments naturels, réalisées par le poète, aboutissent à une « sexualisation » de la nature et parfois à une érotisation de son contact avec l’homme. Sa poésie est un accouplement perpétuel de femmes et d’hommes métamorphosés en animaux, en végétaux ou en pierres, avec des pierres, des plantes et des bêtes métamorphosées en hommes. Le rapport à la nature se trouve ainsi bouleversé, ce contact des corps aboutissant à un décentrement et à un repositionnement de l’homme dans la nature.

Abstract

No Livro das ignorãças, publicado em 1993, Manoel de Barros desvenda o caminho que o leva à criação poética. Como aparece no título do livro, a primeira etapa consiste numa valorização da ignorância, que lhe permite inverter os valores tradicionais, erigindo o esquecimento em sabedoria. Ao mesmo tempo, o poeta exprime no Livro das ignorãças, como no conjunto da sua vasta obra poética, a sua vontade marcada de regressar às origens do Homem. Assim encontra-se apto para fazer nascer delírios frásicos e atingir, numa renovação do olhar sobre o mundo que o circunda, os deslimites da palavra
