Dual Input Quantum Teleportation

We propose a quantum teleportation protocol using two senders and one receiver, referred to as the dual input quantum teleportation (DIQT) protocol. We show that the receiver state is in a combination of both senders’ states. We also show that the DIQT protocol can be modified to a quantum controlled teleportation with two controllers, with one of the controllers having extra control over the fidelity value. The advantages of this controlled protocol are that it can add two controllers by only using a three-qubit channel state, and one of the controllers has extra control over the fidelity value. We also show that the DIQT protocol can be modified to an encrypted quantum teleportation protocol, in which, by using one of two criteria pairs, the actual qubit representing the actual information is encrypted into two qubits different from the actual one and then given to the two senders to be teleported. The receiver will get the actual qubit without having to decrypt, but with the consequence, the probability is less than one. However, this probability value depends on how the actual qubit is encrypted and can be set so that the probability value remains close to one. This protocol has two advantages. First, due to the non-contacting between the senders and the actual qubit, this encrypted teleportation protocol gives more security than other existing protocols. Second, even if the teleportation success probability is less than one, no decryption is required for the recipient to receive the actual qubit.
