Compact quantum gates on electron-spin qubits assisted by diamond nitrogen-vacancy centers inside cavities
Hai-Rui Wei, Fu-Guo Deng
Constructing compact quantum circuits for universal quantum gates on solid-state systems is crucial for quantum computing. We present some compact quantum circuits for a determinis…

Quantum logic gates are the key elements in quantum computing. Here we investigate the possibility of achieving a scalable and compact quantum computing based on stationary electro…
Photonic spatial Bell-state analysis for robust quantum secure direct communication using quantum dot-cavity systems
Bao-Cang Ren, Hai-Rui Wei, Ming Hua +2
Recently, experiments showed that the spatial-mode states of entangled photons are more robust than their polarization-mode states in quantum communications. Here we construct a co…
Deterministic photonic spatial-polarization hyper-controlled-not gate assisted by quantum dot inside one-side optical microcavity
Bao-Cang Ren, Hai-Rui Wei, Fu-Guo Deng
Up to now, all the works about constructing quantum logic gates, an essential part in quantum computing, are focused on operating on one degree of freedom (DOF) of quantum systems.…
Universal quantum gates for hybrid systems assisted by quantum dots inside double-sided optical microcavities
Hai-Rui Wei, Fu-Guo Deng
We present some deterministic schemes to construct universal quantum gates, that is, controlled- NOT, three-qubit Toffoli, and Fredkin gates, between flying photon qubits and stati…
