Abstract:

A scheme to implement quantum Controlled-NOT(CNOT)gates with a resonant cavity is proposed and this quantum gate to carry out teleportation of an arbitrary single-atom superposition state is used. By using three level atoms our scheme can be realized through single-qubit operation and resonant interaction between two atoms and a resonant cavity. The interaction time between two atoms and the single-mode cavity is very short, which is important in view of decoherence. This character is one of the advantages of our scheme comparing to the scheme based on detuned cavity.

Key words: quantum information, quantum CNOT gate, teleportation, resonant cavity
