Controlled Quantum Secure Direct Communication Based on Four-Qubit Cluster States and Quantum Search Algorithm
A controlled quantum secure direct communication protocol based on four-qubit cluster states and quantum search algorithm is put forward, in which four users, a sender, a receiver and two controllers, are involved in achieving the secure transmission of secret message. The four-qubit cluster state c...
