Quantum Cloning

A Universal 1 → 2 Cloner is proposed using cavity QED. This is a deterministic proposal that takes far less steps than previous models, and makes use of dispersive C-NOT gates.

We propose an experimentally feasible scheme to implement the optimal general 1→2 phase-covariant quantum cloning machine based on cavity QED. In the scheme, the cavity is only virtually excited and thus the scheme is insensitive to the cavity field states and cavity decay.
