Ergotropy of quantum many-body scars
Zhaohui Zhi, Qingyun Qian, Jin-Guo Liu +1
Quantum many-body scars break ergodicity and evade thermalization, resulting in sub-volume law entanglement entropy even with high energy density. While their quantum correlations…
Phase-Stable Hologram Updates for Large-Scale Neutral-Atom Array Reconfiguration
Erdong Huang, Jiayi Huang, Hongshun Yao +2
Assembling large-scale, defect-free Rydberg atom arrays is a key technology for neutral-atom quantum computation. Dynamic holographic optical tweezers enable the assembly and recon…
Block Coordinate Descent for Dynamic Portfolio Optimization on Finite-Precision Coherent Ising Machines
Keming He, Yuehan Zhang, Hongshun Yao +2
Coherent Ising machines (CIMs) have emerged as specialized quantum hardware for large-scale combinatorial optimization. However, for large instances that remain challenging for cla…
Encoding computationally hard problems in triangular Rydberg atom arrays
Xi-Wei Pan, Huan-Hai Zhou, Yi-Ming Lu +1
Rydberg atom arrays are a promising platform for quantum optimization, encoding computationally hard problems by reducing them to independent set problems with unit-disk graph topo…
Universal quantum computing with a single arbitrary gate
Zhong-Yi Ni, Yu-Sheng Zhao, Jin-Guo Liu
This study presents a roadmap towards utilizing a single arbitrary gate for universal quantum computing. Since two decades ago, it has been widely accepted that almost any single a…
