We propose a novel protocol for controlled bidirectional quantum secure communication based on a nonlocal swap gate scheme. Our proposed protocol would be applied to a system in which a controller (supervisor/Charlie) controls the bidirectional communication with quantum information or secret messages between legitimate users (Alice and Bob).

In this paper, we propose a communication protocol called Controlled Bidirectional Quantum Secret Direct Communication (CBQSDC) for mobile networks. In mobile networks, telecom companies assist the agent ensuring both sides could receive the other’s secret messages in the transmission by quantum theory simultaneously. This protocol is based on nparticle GHZ(More)
Quantum computing can effectively and efficiently perform dense coding, teleportation, prime factoring, and database search methods. Quantum cryptography can be used in secret sharing, secure computation, and secure direct communications. Cloud computing and e-commerce are also ensured by applying quantum computation. In this article we introduce existing(More)
