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…
High-Dimensional Two-Photon Quantum Controlled Phase-Flip Gate
Mingyuan Chen, Jiangshan Tang, Miao Cai +2
High-dimensional quantum systems have been used to reveal interesting fundamental physics and to improve information capacity and noise resilience in quantum information processing…
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…
Photonic indistinguishability characterization and optimization for cavity-based single-photon source
Miao Cai, Mingyuan Chen, Jiangshan Tang +1
Indistinguishability of single photons from independent sources is critically important for scalable quantum technologies. We provide a comprehensive comparison of single-photon in…
Generation of True Quantum Random Numbers with On-Demand Probability Distributions via Single-Photon Quantum Walks
Chaoying Meng, Miao Cai, Yufang Yang +7
Random numbers are at the heart of diverse fields, ranging from simulations of stochastic processes to classical and quantum cryptography. The requirement for true randomness in th…
