Observation of High-Order Quantum Pancharatnam-Berry Phase with Structured Photons
Shuang-Yin Huang, He Jiang, Zhi-Cheng Ren +6
When a quantum system evolves so that it returns to its initial state, it will acquire a geometric phase acting as a memory of the transformation of a physical system, which has be…

Postselection-Free Cavity-Enhanced Narrow-Band Orbital Angular Momentum Entangled Photon Source
Pei Wan, Wen-Zheng Zhu, Yan-Chao Lou +5
Cavity-enhanced spontaneous parametric down-conversion (SPDC) provides a significant way to produce 10 MHz narrow-band photon pairs, which matches the bandwidth of photon for…

Two-particle quantum interference in a nonlinear optical medium: a witness of timelike indistinguishability
Chao Chen, Shu-Tian Xue, Yu-Peng Shi +8
The Hong-Ou-Mandel effect is a paradigmatic quantum phenomenon demonstrating the interference of two indistinguishable photons that are linearly coupled at a 50:50 beam splitter. H…
