Theory of Deterministic Photon-Loss Subspaces for Quantum Interferences
Yadi Niu, Haoyang Zhang, Zihan Mo +2
Quantum coherence, quantum decoherence, and photon number reduction are coexistent in linear lossy optical systems. However, how these three elements combine together to determine…
Two-Phonon Resonance Drives Multicomponent Mechanical Cat States
Nuo Wang, Haoyang Zhang, Yu Tian +2
Using quadratic optomechanical coupling to prepare high-purity mechanical cat states is not feasible as its strength is several orders weaker than linear optomechanical coupling. H…
Wavefront Control and Intensity Modulation of Third Harmonic Generation in Nonlocal Metasurfaces
Yu Tian, Nuo Wang, Qi Liu +4
Metasurfaces have emerged as a promising platform for integrated nonlinear optics. Nonlocal metasurfaces enable high nonlinear conversion efficiency, while the local ones can offer…
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…
