Temporal Dynamical Quantum Phase Transition in Dicke Model with Trapped Ions
Ji Bian, Wei Wu, Zihan Xie +8
Temporal non-analyticities in the rate function of the Loschmidt echo manifests a class of dynamical quantum phase transitions (DQPTs) that has emerged as a powerful framework for…
Non-Abelian Aharonov-Bohm Caging in Synthetic Dimensions with a Trapped Ion
Wanchao Yao, Sai Li, Zhiyuan Liu +7
Aharonov-Bohm (AB) caging is a complete localization phenomenon in two-dimensional lattices due to destructive interference induced by the background gauge fields. However, current…
Experimental Demonstration of the Timelike Unruh Effect with a Trapped-Ion System
Zhenghao Luo, Yi Li, Xingyu Zhao +3
The Unruh effect predicts that an accelerated observer perceives the Minkowski vacuum as a thermal bath, but its direct observation requires extreme accelerations beyond current ex…
Beating the break-even point with autonomous quantum error correction
Yi Li, Qingyuan Mei, Qing-Xuan Jie +13
Quantum error correction (QEC) is essential for practical quantum computing, as it protects fragile quantum information from errors by encoding it in high-dimensional Hilbert space…
Experimental realization and synchronization of a quantum van der Pol oscillator
Yi Li, Zihan Xie, Xiaodong Yang +8
Classical self-sustained oscillators, that generate periodic motion without periodic external forcing, are ubiquitous in science and technology. The realization of nonclassical sel…
