Scaling of entangling-gate errors in large ion crystals
Wenhao He, Wenhao Zhang, Xiao Yuan +2
Trapped-ion has shown great advantages in building quantum computers. While high fidelity entangling-gate has been realized for few ions, how to maintain the high fidelity for larg…
Continuous phase transition induced by non-Hermiticity in the quantum contact process model
Wen-Bin He, Jiasen Jin, Fernando Iemini +1
Non-Hermitian quantum system recently have attracted a lots of attentions theoretically and experimentally. However, the results based on the single-particle picture may not apply…
Scaling of energy and power in a large quantum battery-charger model
Lei Gao, Chen Cheng, Wen-Bin He +3
We investigate a multi-qubit quantum battery-charger model, focusing on its potential emulation on a superconducting qubit chip. Using a large-spin representation, we first obtain…
Quantum dynamics of Gaudin magnets
Wen-Bin He, Stefano Chesi, H. -Q. Lin +1
Quantum dynamics of many-body systems is a fascinating and significant subject for both theory and experiment. The question of how an isolated many-body system evolves to its stead…
Lower and upper bounds of quantum battery power in multiple central spin systems
Li Peng, Wen-Bin He, Stefano Chesi +2
We study the energy transfer process in quantum battery systems consisting of multiple central spins and bath spins. Here with "quantum battery" we refer to the central spins, wher…
Determination of the critical exponents in dissipative phase transitions: Coherent anomaly approach
Jiasen Jin, Wen-Bin He, Fernando Iemini +4
We propose a generalization of the coherent anomaly method to extract the critical exponents of a phase transition occurring in the steady-state of an open quantum many-body system…
Exact quantum dynamics of XXZ central spin problems
Wen-Bin He, Stefano Chesi, Hai-Qing Lin +1
We obtain analytically close forms of benchmark quantum dynamics of the collapse and revival (CR), reduced density matrix, Von Neumann entropy, and fidelity for the XXZ central spi…
Universal Properties of Fermi Gases in One-dimension
Wen-Bin He, Yang-Yang Chen, Shizhong Zhang +1
In this Rapid Communication, we investigate the universal properties of a spin-polarized two-component Fermi gas in one dimension (1D) using Bethe ansatz. We discuss the quantum ph…
