Quadratic Quantum Speedup for Finding Independent Set of a Graph
Xianjue Zhao, Peiyun Ge, Li You +1
A quadratic speedup of the quantum adiabatic algorithm (QAA) for finding independent sets (ISs) in a graph is proven analytically. In comparison to the best classical algorithm wit…

Coherent Two-State Oscillations in False Vacuum Decay Regimes
Peiyun Ge, Xiao Wang, Yu-Xin Chao +2
Coherent two-state oscillations are observed in numerical simulations of the one-dimensional transverse-longitudinal-field Ising model (TLFIM) within false vacuum decay regimes. St…

Observation of average topological phase in disordered Rydberg atom array
Zongpei Yue, Yu-Feng Mao, Xinhui Liang +8
Topological phases have been extensively studied over the past two decades, primarily in quantum pure states, where they are protected by exact symmetries. Recently, numerous studi…
