Faster State Preparation across Quantum Phase Transition Assisted by Reinforcement Learning
Shuai-Feng Guo, Feng Chen, Qi Liu +6
An energy gap develops near quantum critical point of quantum phase transition in a finite many-body (MB) system, facilitating the ground state transformation by adiabatic paramete…

Multi-parameter estimation with multi-mode Ramsey interferometry
Xinwei Li, Jia-Hao Cao, Qi Liu +2
Estimating multiple parameters simultaneously is of great importance to measurement science and application. For a single parameter, atomic Ramsey interferometry (or equivalently o…

Beating the classical precision limit with spin-1 Dicke state of more than 10000 atoms
Yi-Quan Zou, Ling-Na Wu, Qi Liu +5
Interferometry is a paradigm for most precision measurements. Using uncorrelated particles, the achievable precision for a two-mode (two-path) interferometer is bounded by the…
