Area-Law Entanglement in Quantum Chaotic System
Chunyin Chen, Sizhe Yan, Biao Wu
Entanglement entropy is a fundamental diagnostic for quantum chaos, typically exhibiting volume-law scaling in highly excited eigenstates of chaotic many-body systems. In this work…

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…

Variational method for wavefunctions in spin- PXP model
Zhigang Hu, Biao Wu
We investigate the approach of time-dependent variational principle (TDVP) for the one-dimensional spin- PXP model with detuning, which is relevant for programmable Rydberg atom…
