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…
Three-Photon Polarization Entanglement of Green Light
Yan-Chao Lou, Zhi-Cheng Ren, Chao Chen +8
Recently, great progress has been made in the entanglement of multiple photons at various wavelengths and in different degrees of freedom for optical quantum information applied in…
Heralded High-Dimensional Photon-Photon Quantum Gate
Zhi-Feng Liu, Zhi-Cheng Ren, Pei Wan +10
High-dimensional encoding of quantum information holds the potential to greatly increase the computational power of existing devices by enlarging the accessible state space for fix…
