Entanglement Degree During Generation of Quantum Controlled-NOT Gates

  • Received Date: 17 Sep 2007
  • Publish Date: 25 Apr 2008
  • Generation of quantum controlled-NOT gates consists of sequentially applying three laser pulses to trapped cold ions.The entanglement dynamics during the generation of quantum controlled-NOT gates and the variation in entanglement degrees with time were analyzed.The results show that there is not entanglement between external state and internal state of trapped cold ions in the first and third laser pulses,and there is strong periodic entanglement in the second laser pulse.
