Cold atomic ensembles as quantum antennas for distributed networks of single-atom arrays
Xiaoshui Lin, Yefeng Mei, Chuanwei Zhang
Single neutral atoms in optical tweezer arrays offer a promising platform for high-fidelity quantum computing at local nodes. Nonetheless, creating entanglement between remote node…
Revealing Bosonic Exchange Symmetry in Two-Photon Temporal Wavefunction
Yefeng Mei, Yue Jiang, Shengwang Du
The wavefunction of two identical bosons remains invariant under particle exchange - a fundamental quantum symmetry that underlies Bose-Einstein statistics. We report the direct ex…
Quantum Langevin theory for two coupled phase-conjugated electromagnetic waves
Yue Jiang, Yefeng Mei, Shengwang Du
While loss-gain-induced Langevin noises have been intensively studied in quantum optics, the effect of a complex-valued nonlinear coupling coefficient on the noises of two coupled…
Symmetry Protected Two-Photon Coherence Time
Xuanying Lai, Christopher Li, Alan Zanders +2
We report the observation of symmetry protected two-photon coherence time of biphotons generated from backward spontaneous four-wave mixing in laser-cooled Rb atoms. When bi…
