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…
Quantum Simulation of Oscillatory Unruh Effect with Superposed Trajectories
Xu Cheng, Yue Li, Zehua Tian +3
The Unruh effect predicts an astonishing phenomenon that an accelerated detector would detect counts despite being in a quantum field vacuum in the rest frame. Since the required d…
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…
Programmable simulation of high-order exceptional point with a trapped ion
Yue Li, Yang Wu, Yuqi Zhou +9
The nontrivial degeneracies in non-Hermitian systems, exceptional points (EPs), have attracted extensive attention due to intriguing phenomena. Compared with commonly observed seco…
