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…
Quantum Hamiltonian Algorithms for Maximum Independent Sets
Xianjue Zhao, Peiyun Ge, Hongye Yu +3
With qubits encoded into atomic ground and Rydberg states and situated on the vertexes of a graph, the conditional quantum dynamics of Rydberg blockade, which inhibits simultaneous…
Quantum Entanglement and Chocolates
Biao Wu
Two statistical ensembles of chocolates are constructed to mimic two quantum entangled states, the spin singlet state and the GHZ state. Despite great efforts to achieve the closes…
