Scheme to implement optimal asymmetric economical 1→3 phase-covariant telecloning via cavity QED

doi:10.1088/1674-1056/19/8/080309

Abstract We propose an experimentally feasible scheme to implement the optimal asymmetric economical 1→3 phase-covariant telecloning protocol, which works without ancilla, based on cavity quantum electrodynamics (QED). The scheme is insensitive to the cavity field states and the cavity decay. In the telecloning process, the cavity is only virtually excited, it greatly prolongs the efficient decoherent time. Therefore, the scheme may be experimentally realized in the field of current cavity QED techniques.
