Quantum Simulation of Spin-Dependent Electron Transfer in a Synthetic Chiral Lattice with a Trapped Ion
Yi Li, Chuyuan Chen, Xingyu Zhao +8
Electron transfer through chiral structures can exhibit spin asymmetry, known as the chiral-induced spin selectivity effect, whose microscopic origin remains an open question. Whil…
Unique continuation inequalities for the Dunkl-Schrödinger equation via uncertainty principles
Xingyu Zhao, Hui Xu, Zhiwen Duan
In this paper, we establish unique continuation inequalities at two time points for the Dunkl--Schrödinger equation. The proof is based on quantitative uncertainty principles 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…
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…
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…
