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…
