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…
Conversion of photon temporal shape using single gradient metasurface
Zhaohua Tian, Qi Liu, Yu Tian +1
By applying phase modulation across different frequencies, metasurfaces possess the ability to manipulate the temporal dimension of photons at the femtosecond scale. However, there…
Near-symmetric multiport beam splitting for high-NOON state preparation on nonlocal metasurface
Yu Tian, Qi Liu, Zhaohua Tian +2
Polarization beam splitting (BS) has been implemented on gradient metasurface with local response for entanglement manipulation and state reconstruction. To realize more degrees of…
Wavepacket interference of two photons through a beam splitter: from temporal entanglement to wavepacket shaping
Zhaohua Tian, Qi Liu, Yu Tian +1
Quantum interferences based on beam splitting are widely used for entanglement. However, the quantitative measurement of the entanglement in terms of temporal modes and wavepacket…
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…
