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.

We propose a scheme to secret sharing of an unknown N-atom entangled state in driven cavity QED. The scheme needs only atomic Bell states as the quantum channels and joint Bell-state measurement is unnecessary. In addition, the scheme is insensitive to the cavity decay and the thermal field.

Einstein Podolsky Rosen

A quantum authentication scheme is presented in this paper. Two parties share Einstein-Podolsky-Rosen(EPR) pairs previously as the identification token. They create auxiliary EPR pairs to interact with the identification token. Then the authentication is accomplished by a complete Bell state measurement. This scheme is proved to be secure. If no errors and eavesdroppers exist in the transmission, the identification token is unchanged after the authentication. So it can be reused.
