Bidirectional teleportation for underwater quantum communications

In this work, we evaluate the performance of a bidirectional teleportation protocol on an IBM Q Experience quantum processor of six or more qubits. Moreover, we analyze the viability in the implementation of the mentioned protocol in a configuration composed by two submerged nuclear submarines on opposite sides of the ocean and a satellite that generates and distributes entangled pairs, and transmits optical bits of disambiguation to those buoys located on the sea surface, and associated to those submerged submarines. The results of the implementations on a 16-qubits Melbourne IBM Q processor turned out to be extremely satisfactory with a low margin of error considering that this processor does not belong to the Premium family of IBM Q, which implies a high presence of decoherence and sensitivity to flip errors even in few-gate quantum circuits.
