Photonic two-qubit parity gate with tiny cross-Kerr nonlinearity
Xin-Wen Wang, Deng-Yu Zhang, Shi-Qing Tang +3
The cross-Kerr nonlinearity (XKNL) effect can induce efficient photon interactions in principle with which photonic multiqubit gates can be performed using far fewer physical resou…
Optimal ancilla-free phase-covariant telecloning of qudits via nonmaximally entangled states
Xin-Wen Wang, Guo-Jian Yang
We study the one-to-two phase-covariant telecloning of a qudit without ancilla. We show that the fidelity of the two clones can reach that of the clones in the optimal ancilla-base…
Remote information concentration and multipartite entanglement in multilevel systems
Xin-Wen Wang, Deng-Yu Zhang, Guo-Jian Yang +2
Remote information concentration (RIC) in -level systems (qudits) is studied. It is shown that the quantum information initially distributed in three spatially separated qudits…
Multiparty hierarchical quantum-information splitting
Xin-Wen Wang, Deng-Yu Zhang, Shi-Qing Tang +1
We propose a scheme for multiparty hierarchical quantum-information splitting (QIS) with a multipartite entangled state, where a boss distributes a secret quantum state to two grad…
