Quantum dialogue by using the two-qutrit entangled states. (English) Zbl 1180.81033
Summary: A protocol for quantum dialogue is proposed to exchange directly the communicators’ secret messages by using the two-qutrit entangled state. In this protocol, the security of communication is ensured by the secret transmitting order of qutrits. It is shown that two legitimate users can directly transmit the secret messages by generalized Bell-basis measurement and classical communication.
