Controlled dense coding using the Greenberger-Horne-Zeilinger state
Abstract
In this paper we investigate the dense coding with a three-particle entangled state. In this case one party (Alice) can send information to the second party (Bob), whereas the local measurement of the third party (Cliff) serves as quantum erasure. The quantum channel between Alice and Bob is controlled by Cliff via the measurement.
