摘要：
An alternative scheme is proposed in this paper to realize an n-qubit Fredkin gate with superconducting quantum-interference device ( SQUID) in cavity QED. The multiqubit logical gate is essentially accomplished by a sequence of operations on only two SQUIDs in a large-detuned cavity. In the scheme, the two logical states of a qubit are presented by the two lowest states of a SQUID and the cavity is always in vacuum state so that the limit on the cavity is not serious.
