Realization of universal quantum cloning with superconducting quantum-interference device qubits in a cavity

We propose a scheme to realize a $1\ensuremath{\rightarrow}2$ universal quantum cloning machine with superconducting quantum interference device qubits, embedded in a high-$Q$ cavity. The controlled-NOT operations are derived to present our scheme, and the two-photon Raman resonance processes are used to increase the operation rate. Compared with previous works, our scheme has advantages in the experimental realization and further utilization.
