Fractal Uncertainty and Quantitative Uniqueness for the Fourier Bessel Transform
Xingyu Zhao, Longben Wei, Zhiwen Duan
We establish quantitative uniqueness and a fractal uncertainty principle for the Fourier Bessel transform. In arbitrary dimension, we prove a quantitative uniqueness estimate on re…
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 t…
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…
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…

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…
An energy efficient quantum-enhanced machine
Waner Hou, Xingyu Zhao, Kamran Rehan +5
Quantum friction, a quantum analog of classical friction, reduces the performance of quantum machines, such as heat engines, and makes them less energy efficient. We here report th…
