REALIZATION OF QUANTUM LOGIC GATES AND CLUSTER STATES WITH SUPERCONDUCTING QUANTUM-INTERFERENCE DEVICES

摘要

We propose a method for realizing quantum logic gates and cluster states with superconducting quantum-interference devices (SQUIDs) in cavity QED via Raman transition. In this proposal, quantum logic gates and cluster states are realized by using only two lower flux states of the SQUID system and the excited state would not be excited. Therefore, the effect of decoherence caused by the levels of the SQUID system is possibly minimized.
