主 题：optimal 1→ 3 optimal phase-covariant quantum cloning real state cloning superconducting quantum interference devices
摘 要：We propose a unified scheme to implement the optimal 1→ 3economical phase-covariant quantum cloning and optimal 1→3 economical real state cloning with superconducting quantum interference devices (SQUIDs) in a *** this process,no transfer of quantum information between the SQUIDs and cavity is *** cavity field is only virtually *** scheme is insensitive to cavity ***,the scheme can be experimentally realized in the range of current cavity QED techniques.
