Quantum optics on a chip

QuantuM Optics correlations on a chip

cavity quantum electrodynamics describes the behaviour of a quantum emitter inside an optical cavity, and is one of the few realizable experimental systems in which the coherent interaction between the emitter and the cavity mode can exceed dissipative and dephasing processes. Recent advances in this field include the observation of vacuum Rabi splitting1–3, interference4, upconversion5 and the...

Active 2D materials for on-chip nanophotonics and quantum optics

Two-dimensional materials have emerged as promising candidates to augment existing optical networks for metrology, sensing, and telecommunication, both in the classical and quantum mechanical regimes. Here, we review the development of several on-chip photonic components ranging from electro-optic modulators, photodetectors, bolometers, and light sources that are essential building blocks for a...

Single-Photon Quantum Contextuality on a Chip

In classical physics, properties of objects exist independently of the context, i.e., whether and how measurements are performed. Quantum physics showed this assumption to be wrong, and that Nature is indeed "contextual". Contextuality has been observed in the simplest physical systems, such as single particles, and plays fundamental roles in quantum computation advantage. Here, we demonstrate ...
