Robust Multiple-Range Coherent Quantum State Transfer
B. Chen, Y. D. Peng, Y. Li +1
We propose a multiple-range quantum communication channel to realize coherent two-way quantum state transport with high fidelity. In our scheme, an information carrier (a qubit) an…

Hybridizing collective spin excitations and a cavity with high cooperativity provides a new research subject in the field of cavity quantum electrodynamics and can also have potent…
Quantum signature for laser-driven correlated excitation of Rydberg atoms
Huaizhi Wu, Yong Li, Zhen-Biao Yang +1
The excitation dynamics of a laser-driven Rydberg gas exhibits a cooperative effect due to the interatomic Rydberg-Rydberg interaction, but the large many-body system with inhomoge…
Ground-state phase diagram of the quantum Rabi model
Zu-Jian Ying, Maoxin Liu, Hong-Gang Luo +2
The Rabi model plays a fundamental role in understanding light-matter interaction. It reduces to the Jaynes-Cummings model via the rotating-wave approximation, which is applicable…
Nonreciprocal conversion between microwave and optical photons in electro-optomechanical systems

Z. H. Wang, Q. Zheng, Xiaoguang Wang +1
We study the energy level crossing behavior in two-dimensional quantum well with the Rashba and Dresselhaus spin-orbit couplings (SOCs). By mapping the SOC Hamiltonian onto an anis…
Dynamical invariants in non-Markovian quantum state diffusion equation
Da-Wei Luo, P. V. Pyshkin, Chi-Hang Lam +4
We find dynamical invariants for open quantum systems described by the non-Markovian quantum state diffusion (QSD) equation. In stark contrast to closed systems where the dynamical…
Quantum Langevin approach for non-Markovian quantum dynamics of the spin-boson model

We introduce and analyze a novel mean-field model for polariton condensates with velocity dependence of the effective polariton mass due the photon and exciton components. The effe…
Objectivity in quantum measurement
Sheng-Wen Li, C. Y. Cai, X. F. Liu +1
The objectivity is a basic requirement for the measurements in the classical world, namely, different observers must reach a consensus on their measurement results, so that they be…
