Ripple Signatures of Majorana Hybridization across a Topological Quantum Quench
Xin-Xin Wang, Jin-Xin Li, Ya-Wen Tang +5
The crossover between topology and nonequilibrium dynamics has emerged as a rich frontier, in which quantum systems can exhibit unique dynamical phenomena that lie beyond the reach…
Simultaneous estimation of relative phase and coherence in astronomical interferometry
Yawen Tang, Wei Ye, Lu Qin +6
Astronomical interferometry is a cornerstone technique for high-resolution stellar imaging and observational astrophysics, extracting spatial information from the coherence of ligh…
Impact of the Unruh effect on the estimation precision of Gaussian channel parameters
Shoukang Chang, Yawen Tang, Wei Ye +3
Gaussian quantum channels constitute a pivotal physical framework for characterizing the dynamics of Gaussian quantum states. Extensive scholarly attention has been devoted to the…
Multiparameter quantum estimation with a uniformly accelerated Unruh-DeWitt detector
Shoukang Chang, Yashu Yang, Wei Ye +6
The uniformly accelerated Unruh-DeWitt detector serves as a fundamental model in relativistic quantum metrology. While previous studies have mainly concentrated on single-parameter…
