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…
High-fidelity two-qubit quantum logic gates in a trapped-ion chain using axial motional modes
Xingyu Zhao, Ji Bian, Yi Li +3
Trapped-ion systems are one of the leading platforms for quantum information processing, where a key challenge is to scale up system size while maintaining high-fidelity two-qubit…
Experimental Proposal on Non-Abelian Aharonov-Bohm Caging Effect with a Single Trapped Ion
Zhiyuan Liu, Wanchao Yao, Sai Li +4
In the lattice system, when the synthetic flux reaches a phase along a closed loop under the synthetic gauge field, destructive interference occurs and gives rise to the local…
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…
