What does governance look like ‘from below’ – from the perspectives of poor and marginalised households? How do patterns of conflict affect that? These were the questions at the heart of the Governance at the Margins research project. Over three years from 2017-2020 we worked to explore this through in-depth study in conflict-affected areas of Mozambique, Myanmar, and Pakistan. Our research teams interviewed the same people regularly over that time, finding out how they resolved problems and interacted with authorities. In this paper we connect what we found to the realities and complexities of development practice, drawing on the input of 20 experienced practitioners working in bilateral and multilateral development agencies and international NGOs, who generously gave their time to help us think through the practical implications of our wealth of findings., This paper is also published on the Institute of Development Studies website.

The outbreak of the COVID-19 pandemic was an unprecedented event in the modern era. Earlier studies demonstrated how ‘critical junctures’, which comprise major historical events and emergencies, often play an essential role in social change. This paper seeks to explore whether the COVID-19 pandemic would prove to be a similar pivotal moment, and what lessons and insights we could gather for positive social change., The research set out to find key insights on how individuals, communities, and organizations in civil society were responding to the pandemic in low-income populations at the intersection of multiple inequalities. These lessons could inform how donors, governments and NGOs might reshape their efforts to reduce emerging or deepening inequalities, and how civil society organisations and community-based organisations could amplify their positive impacts., Over 18 months, from September 2020 to March 2022, the ‘Emergent Agency’ research convened a global conversation between activists, development practitioners, researchers, and academics to better understand the phenomena that were taking place in response to the pandemic. The research collected more than 200 case studies and held a series of webinars and conversations in thematic clusters to uncover what these responses could teach us. The research project was enabled with funding from The Atlantic Fellows for Social and Economic Equity programme (AFSEE) of the London School of Economics., The findings from the collaborative research have been summarised in two main documents, - this research report, which retraces the steps of the study, its methodology and main findings;, - and a brief, which summarizes key points that we believe are important for those working in international and national NGOs, and donor agencies.

Transitioning from quantum computation on physical qubits to quantum computation on encoded, logical qubits can improve the error rate of operations, and will be essential for realizing valuable quantum computational advantages. Using a neutral atom quantum processor with 256 qubits, each an individual Ytterbium atom, we demonstrate the entanglement of 24 logical qubits using the distance-two [[4,2,2]] code, simultaneously detecting errors and correcting for lost qubits. We also implement the Bernstein-Vazirani algorithm with up to 28 logical qubits encoded in the [[4,1,2]] code, showing better-than-physical error rates. We demonstrate fault-tolerant quantum computation in our approach, guided by the proposal of Gottesman (2016), by performing repeated loss correction for both structured and random circuits encoded in the [[4,2,2]] code. Finally, since distance-two codes can correct qubit loss, but not other errors, we show repeated loss and error correction using the distance-three [[9,1,3]] Bacon-Shor code. These results begin to clear a path for achieving scientific quantum advantage with a programmable neutral atom quantum processor., Comment: 17 pages, 16 figures

We introduce an optical tweezer platform for assembling and individually manipulating a two-dimensional register of nuclear spin qubits. Each nuclear spin qubit is encoded in the ground $^{1}S_{0}$ manifold of $^{87}$Sr and is individually manipulated by site-selective addressing beams. We observe that spin relaxation is negligible after 5 seconds, indicating that $T_1\gg5$ s. Furthermore, utilizing simultaneous manipulation of subsets of qubits, we demonstrate significant phase coherence over the entire register, estimating $T_2^\star = \left(21\pm7\right)$ s and measuring $T_2^\text{echo}=\left(42\pm6\right)$ s., Comment: 10 pages, 4 figures
