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…
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…
Entanglement distillation for quantum communication network with atomic-ensemble memories
Tao Li, Guo-Jian Yang, Fu-Guo Deng
Atomic ensembles are effective memory nodes for quantum communication network due to the long coherence time and the collective enhancement effect for the nonlinear interaction bet…
Universal quantum gates on microwave photons assisted by circuit quantum electrodynamics
Ming Hua, Ming-Jie Tao, Fu-Guo Deng
Based on a microwave-photon quantum processor with two superconducting resonators coupled to one transmon qutrit, we construct the controlled-phase (c-phase) gate on microwave-phot…
