We propose a more efficient and reliable scheme for transferring quantum states between distant atoms than previous schemes based on resonant atom-cavity interaction.In addition,our system can also be used to implemen...
A protocol is proposed to implement a three-qubit phase gate for photonic qubits in a three-mode cavity. The idea can be extended to directly implement a N-qubit phase gate. We also show that the interaction time rema...

Based on the Josephson charge qubits coupled through microwaves, a scheme for implementation of the Deuutsch-Jozsa algorithm is proposed under the present scalable and feasible microfabrication technique. It would be ...
A design approach for optical interconnect system and beam splitting composed of a phase-only diffractive optical element is described.The diffractive optical element is of 16 phase levels,so its efficiency may reach ...
