Breeding the Cat Through Superposition of Two Schrodinger Kittens Based on Coupled Waveguides
Nuo Wang, Xinchen Zhang, Qi Liu +3
Optical Schrodinger's cat (SC) is highly anticipated because of the potential of realizing fault-tolerant quantum computing, but the practical merit is only shown when the amplitud…

Quantum PT-Phase Diagram in a Non-Hermitian Photonic Structure
Xinchen Zhang, Yun Ma, Qi Liu +7
Photonic structures have an inherent advantage to realize PT-phase transition through modulating the refractive index or gain-loss. However, quantum PT properties of these photonic…

Gain-gain and gain-lossless PT-symmetry broken from PT-phase diagram
Qi Zhang, Yun Ma, Qi Liu +5
Parity-time (PT) symmetry and broken in micro/nano photonic structures have been investigated extensively as they bring new opportunities to control the flow of light based on non-…
