Quantum Cross Nonlinearity for Photon-Number-Resolving Nondestructive Detection
Jiang-Shan Tang, Mingyuan Chen, Miao Cai +4
We present an unconventional mechanism for quantum nonlinearity in a system comprising of a V-type quantum emitter (QE) and two Fabry-Perot cavities. The two transitions of the V-t…

Nonreciprocal PT-symmetric phase transition in a non-Hermitian chiral quantum optical system
Miao Cai, Jiang-Shan Tang, Ming-Yuan Chen +1
Phase transitions, non-Hermiticity and nonreciprocity play central roles in fundamental physics. However, the triple interplay of these three fields is of lack in the quantum domai…
