Logical Gate

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.

Squid System

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.
