Detection of entangled states supported by reinforcement learning
Jia-Hao Cao, Feng Chen, Qi Liu +4
Discrimination of entangled states is an important element of quantum enhanced metrology. This typically requires low-noise detection technology. Such a challenge can be circumvent…
Cyclic nonlinear interferometry with entangled non-Gaussian spin states
Qi Liu, Tian-Wei Mao, Ming Xue +2
We propose an efficient nonlinear readout scheme for entangled non-Gaussian spin states (ENGSs) based on the intrinsic quasi-cyclic dynamics of interacting spin-1/2 systems. We foc…
Quantum enhanced sensing by echoing spin-nematic squeezing in atomic Bose-Einstein condensate
Tian-Wei Mao, Qi Liu, Xin-Wei Li +6
Quantum entanglement can provide enhanced precision beyond standard quantum limit (SQL), the highest precision achievable with classical means. It remains challenging, however, to…
Nonlinear interferometry beyond classical limit facilitated by cyclic dynamics
Qi Liu, Ling-Na Wu, Jia-Hao Cao +5
Time-reversed evolution has substantial implications in physics, including prominent applications in refocusing of classical waves or spins and fundamental researches such as quant…
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…
