An experimentally feasible scheme for implementing quantum secret sharing via cavity quantum electrodynamics (QED) is proposed. The scheme requires the large detuning of the cavity field from the atomic transition, the cavity is only virtually excited, thus the requirement on the quality factor of the cavity is greatly loosened.

We propose a protocol for implementing quantum secret sharing via EPR states in driven cavity QED. Both of the two receivers can read out the sender's secret if they cooperate. The protocol does not require the joint Bell-state measurement needed in the previous schemes. In the protocol the cavity is only virtually excited and thus the requirement on the quality factor of the cavity is greatly loosened.
