Implementation of a Controlled-NOT Gate Using Superconducting Quantum Interference Devices

  • Received Date: June 06, 2007
  • Published Date: January 31, 2008
  • A scheme is proposed for implementing a controlled-NOT gate via superconducting quantum interference device (SQUID) in cavity-QED. The controlled-NOT gate can be achieved by coupling the SQUID to a single-mode microwave cavity field or classical microwave pluses. The scheme may be
    experimentally realizable.
