Phase Analysis on the Error Scaling of Entangled Qubits in a 53-Qubit System
The phase trajectory of an entangled evolution, and the impact of the sudden death of GHZ-like states and the revival of newly excited states are analyzed in details.

A variational quantum algorithm for Hamiltonian diagonalization
To obtain the full spectrum of the Hamiltonian, we use a quantum imaginary time evolution algorithm with high temperature, which prepares a thermal state with a small correlation length.
Quantum Physics
Upper bounds for relative entropy of entanglement based on active learning
Quantifying entanglement for multipartite quantum state is a crucial task in many aspects of quantum information theory.
