1. Localization by Disordered Gauge Fields

Author

Shruti Jayaprakash Saiji, Konrad Tschernig, Lukas Maczewsky, Alexander Szameit, Armando Perez-Leija, and Miguel A. Bandres

Abstract

We show that it is possible to induced Anderson localization in an optical lattice with no disorder in their couplings or index of refraction but by a disordered artificial gauge field generated by periodic driving.

3. Splitting exceptional points by photon-number resolved detection of multi-mode coherent states

Author

Armando Perez-Leija, Konrad Tschernig, and Kurt Busch

Subjects
Quantum optics, Physics, Photon, business.industry, Physics::Optics, Lossy compression, law.invention, Computational physics, law, Coherent states, Photonics, Phase conjugation, business, Waveguide, Beam splitter
Abstract

We show theoretically that lossy waveguide systems exhibit exceptional points, whose order is enhanced by the photon number resolved detection of their coherent exceptional modes.

4. Topological protection versus degree of entanglement of two-photon edge states

Author

Konrad Tschernig, Kurt Busch, and Armando Perez-Leija

Subjects
Physics, Photon, Degree (graph theory), business.industry, Dephasing, Topological insulator, Quantum Physics, Quantum entanglement, Edge states, Photonics, Photonic lattices, Topology, business
Abstract

We investigate theoretically the physical mechanisms that contribute to the vulnerability of highly entangled two-photon edge states propagating in topological insulator photonic lattices. We present clear guidelines for maximizing entanglement without sacrificing topological protection.

Abstract

It is widely accepted that photons are bosons. To the best of our knowledge, we present the first-ever test of this fundamental assumption of quantum electrodynamics and discuss the influence of experimental imperfections.

Abstract

We demonstrate generation of entangled photon-subtracted states and manipulation of their quantum fluctuations. The flexibility of our technique allows us to explore Hong-Ou-Mandel interferometry with mesoscopic states that resemble systems of entangled lasers.

Abstract

The Aharonov-Anandan phase is a generalization of the Berry phase and so far its observation in photonics has been elusive. Here work we report on measurements of Aharonov-Anandan phases using driven harmonic oscillator photonic lattices.
