摘要：
A protocol for the quantum stretching of an arbitrary state among three nonlocal qubits is proposed in this paper. When this protocol is used for making a quantum stretching of a computational basis state (CBS), automatically the same CBS is shared for the three qubits, and this fact can be interpreted as a nonlocal post-processing procedure to transmit such state between sender and receiver without a classical disambiguation channel like that employed in the quantum teleportation protocol. This study has the corresponding theoretical deduction of the proposed protocol, and a couple of implementations, where the first one is made on a quantum simulator, while the second one is carried out on an optical table. Finally, explanations are tested from four points of view to justify the operation of the protocol within Special Relativity without resorting to faster-than-light arguments.
