Hyperentanglement purification and concentration assisted by diamond NV centers inside photonic crystal cavities
Bao-Cang Ren, Fu-Guo Deng
Hyperentanglement has attracted much attention for its fascinating applications in quantum communication. However, it is impossible to purify a pair of photon systems in a mixed hy…
Hyper-parallel photonic quantum computation with coupled quantum dots
Bao-Cang Ren, Fu-Guo Deng
It is well known that a parallel quantum computer is more powerful than a classical one. So far, there are some important works about the construction of universal quantum logic ga…
Hyperentanglement concentration for two-photon four-qubit systems with linear optics
Bao-Cang Ren, Fang-Fang Du, Fu-Guo Deng
Hyperentanglement, defined as the entanglement in several degrees of freedom (DOFs) of a quantum system, has attracted much attention recently. Here we investigate the possibility…
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.…
