High-bandwidth Coherence Cloning using Optical-Phase-Locking Feedforward
Chen Jia, Zhen-Xing Hua, Yu-Xin Chao +1
Ultra-narrow-linewidth lasers with suppressed high-frequency phase noise are critical for quantum control and precision metrology. While optical phase locking (OPL) is the standard…
Coherent Two-State Oscillations in False Vacuum Decay Regimes
Peiyun Ge, Xiao Wang, Yu-Xin Chao +2
Coherent two-state oscillations are observed in numerical simulations of the one-dimensional transverse-longitudinal-field Ising model (TLFIM) within false vacuum decay regimes. St…
Feedforward Cancellation of High-Frequency Phase Noise in Frequency-Doubled Lasers
Zhen-Xing Hua, Yu-Xin Chao, Chen Jia +3
The cancellation of high-frequency laser phase noise using feedforward techniques, as opposed to feedback methods, has achieved significant advancements in recent years. However, d…
Observation of anomalous information scrambling in a Rydberg atom array
Xinhui Liang, Zongpei Yue, Yu-Xin Chao +4
Quantum information scrambling, which describes the propagation and effective loss of localinformation, is crucial for understanding the dynamics of quantum many-body systems. We r…
