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…

Theory of Symmetry-Protected Two-Photon Coherence
Xuanying Lai, Shengwang Du, Yue Jiang
In a recent article [Phys. Rev. Lett. 133, 033601 (2024)], the coherence time of degenerate entangled photon pairs (biphotons) generated via backward spontaneous four-wave mixing i…
