Title: Implementing an ancilla-free 1{yields}M economical phase-covariant quantum cloning machine with superconducting quantum-interference devices in cavity QED

Abstract

We propose a simple scheme to realize 1{yields}M economical phase-covariant quantum cloning machine (EPQCM) with superconducting quantum interference device (SQUID) qubits. In our scheme, multi-SQUIDs are fixed into a microwave cavity by adiabatic passage for their manipulation. Based on this model, we can realize the EPQCM with high fidelity via adiabatic quantum computation.
