Multi-Party Quantum Teleportation with Selective Receiver

Quantum teleportation is the protocol of transmitting quantum states without physically moving them. After the proposal for the first scheme of quantum teleportation in 1993, different schemes have been proposed, according to the application required. In this paper, a new quantum teleportation protocol is proposed for an arbitrary number of users. First, an initial entangled stated made of n + 1 qubits is distributed between the sender and n users. In each run, the sender decides which user is the receiver of the transmitted state. The receiver can retrieve the sent state with the collaboration of the other users. The applications of this protocol are in quantum networks, cloud computing and also quantum cryptography.

Automated summary

The article introduces a new quantum teleportation protocol for an arbitrary number of users, distributing entangled states to achieve transmission. The sender selects the receiver and collaborates with other users to transmit the state to the receiver. Applications of this protocol include quantum networks, cloud computing, and quantum cryptography.
