Switch Mechanism on a Quantum Teleportation Protocol with Dual Controllers

Abstract

In this work, we evaluate one qubit quantum controlled teleportation with two controllers and propose a novel switch mechanism. We show that the teleportation has two scenarios: the first scenario is similar to the OR logic gate, i.e., the teleportation success with the cooperation of one of the controllers only, and it does not matter which one, while the second scenario is similar to the AND logic gate, i.e., the teleportation success if both controllers cooperate. The properties of logic gates come from the nature of the channel state’s entanglement, especially how they preserve their entanglement due to computational bases measurement. We also proposed a switch mechanism for the controllers as a way how to control the teleportation process. We show that if the controller does not allow teleportation, the sender’s qubit information already mixed on the channel vanishes. We also show that it is possible to use the proposed mechanism for other quantum controlled teleportation protocols. Furthermore, we also simulate the OR-logic-gate protocol with the proposed mechanism in Qiskit and show that it can be implemented well.
