Error-heralded generation and self-assisted complete analysis of two-photon hyperentangled Bell states assisted by single-sided quantum-dot-cavity systems
Yan-yan Zheng, Lei-xia Liang, Mei Zhang
Hyperentangled Bell-state analysis (HBSA) is critical for high-capacity quantum communication. Here we design two effective schemes for error-heralded deterministic generation and…

Longitudinal relaxation of a nitrogen-vacancy center in a spin bath by generalized cluster-correlation expansion method
Zhi-Sheng Yang, Yan-Xiang Wang, Ming-Jie Tao +4
We theoretically study the longitudinal relaxation of a nitrogen-vacancy (NV) center surrounded by a 13C nuclear spin bath in diamond. By incorporating electron spin in the cluster…

Complete deterministic multi-electron Greenberger-Horne-Zeilinger state analyzer for quantum communication
Hai-Rui Wei, Bao-Cang Ren, Mei Zhang +2
We present a scheme for the multi-electron Greenberger-Horne-Zeilinger (GHZ) state analyzer, resorting to an interface between the polarization of a probe photon and the spin of an…
