Quantum trajectories under frequent measurements in non-Markovian environment
Luting Xu, Xin-Qi Li
In this work we generalize the quantum trajectory (QT) theory from Markovian to non-Markovian environments. We model the non-Markovian environment by using a Lorentzian spectral de…
Universal hyperparallel hybrid photonic quantum gates with dipole-induced transparency in the weak-coupling regime
Bao-Cang Ren, Guan-Yu Wang, Fu-Guo Deng
We present the dipole induced transparency (DIT) of a diamond nitrogen-vacancy center embedded in a photonic crystal cavity coupled to two waveguides, and it is obvious with the ro…
Heralded quantum repeater for a quantum communication network based on quantum dots embedded in optical microcavities
Tao Li, Guo-Jian Yang, Fu-Guo Deng
We propose a heralded quantum repeater protocol based on the general interface between the circularly polarized photon and the quantum dot embedded in a double-sided optical microc…
Experimental implementation of adiabatic passage between different topological orders
Xinhua Peng, Zhihuang Luo, Supeng Kou +2
Topological orders are exotic phases of matter existing in strongly correlated quantum systems, which are beyond the usual symmetry description and cannot be distinguished by local…
Fast universal quantum gates on microwave photons with all-resonance operations in circuit QED
Ming Hua, Ming-Jie Tao, Fu-Guo Deng
Stark shift on a superconducting qubit in circuit quantum electrodynamics (QED) has been used to construct universal quantum entangling gates on superconducting resonators in previ…
Two-step hyperentanglement purification with the quantum-state-joining method
Bao-Cang Ren, Fang-Fang Du, Fu-Guo Deng
Hyperentanglement is a promising resource in quantum information processing, especially for increasing the channel capacity of long-distance quantum communication. Hyperentanglemen…
