Abstract
The Josephson effects that arise when two quantum states are coupled through a barrier are difficult to observe in optical systems because photon–photon interactions are so weak. Researchers have now demonstrated an optical realization of two such phenomena—macroscopic self-trapping and Josephson oscillations—using polariton condensates in overlapping microcavities.

Two coupled nonlinear cavities in a driven-dissipative environment

TL;DR: In this article, two coupled nonlinear cavities that are coherently driven in a dissipative environment were investigated and a set of analytical solutions for the steady-state correlation functions by using the complex $P$ representation were presented.

Neuromorphic Binarized Polariton Networks.

TL;DR: In this article, an optical network of nodes performing binary operations is proposed, where the nonlinearity required for efficient computation is provided by semiconductor microcavities in the strong quantum light-matter coupling regime, which exhibit excitonpolariton interactions.

Transport of neutral optical excitations using electric fields

TL;DR: In this paper, the Coulomb drag effect of mobile quantum impurities interacting with a fermionic bath form quasiparticles known as Fermi polarons, and the authors demonstrate that a force applied to the bath particles can generate a drag force of similar magnitude acting on the impurities.

Maximizing entanglement in bosonic Josephson junctions using shortcuts to adiabaticity and optimal control

TL;DR: In this paper, the authors consider a bosonic Josephson junction, a model system composed of two coupled nonlinear quantum oscillators which can be implemented in various physical contexts, initially prepared in a product of weakly populated coherent states, and quantify the maximum achievable entanglement between the modes of the junction and then use shortcuts to adiabaticity.

Strongly interacting polaritons in coupled arrays of cavities

TL;DR: In this article, a system of polaritons held in an array of resonant optical cavities, which could be realized using photonic crystals or toroidal microresonators, was shown to form a strongly interacting many-body system showing quantum phase transitions, where individual particles can be controlled and measured.

Coherent oscillations between two weakly coupled Bose-Einstein condensates: Josephson effects, π oscillations, and macroscopic quantum self-trapping

TL;DR: In this paper, coherent atomic oscillations between two weakly coupled Bose-Einstein condensates are discussed, where the weak link is provided by a laser barrier in a (possibly asymmetric) double-well trap or by Raman coupling between two Condensates in different hyperfine levels.
