“…Two cascade splitting modules are applied, one between qubits q [4] and q[0] (pink), and one between qubits q [5] and q [8] (blue). In this way, thanks to both modules, the transition (quantum stretching) takes place from the Bell state 00  to the state 9 GHZ .…”

“…Thus, while at the output of the second Type-I crystal we obtain a Bell state of the 00 type where the photons of both beams (qubits q [4] and q [5]) are entangled, the action of both cascade splitting modules will give rise to a state of the type 9 GHZ shared by the nine output qubits of the complete configuration, that is, by qubits q[0] to q [8].…”

“…Originally, both protocols shared the same limitations, i.e., both are unidirectional and can only transmit information corresponding to the distribution of a single EPR (Einstein-Podolsky-Rosen) pair. In recent years, several versions particularly oriented to the bidirectionally of the quantum teleportation protocol have been proposed [2][3][4][5][6][7][8]. However, the possibility of teleporting several states at the same time, as well as the simultaneous transmission of several bits through an improved version of the superdense coding protocol, is still pending in the literature.…”

In this study, we present a simplified version of the quantum teleportation protocol for nqubits and a generalized version of the superdense coding protocol for n-bits; in both cases, thanks to the cascade splitting technique. Both protocols will be analyzed on three notably different platforms: Quirk simulator, IBM QASM simulator of the IBM Q Experience program, and an optical table. The experiments on the three platforms show the excellent performance of both protocols. Finally, an analysis, about the immunity of these protocols in the presence of an eavesdropper is incorporated.

“…Of all the quantum communications protocols developed to date, quantum teleportation and super-dense coding 17 are the first and most important. Countless efforts have been made during the last two decades to extend the applicability of these protocols to: transmit multiple qubits at the same time 18 , 19 , transmit the qubits in both directions 20 – 26 , and simplify its physical implementation 27 – 31 . …”

In this study, a simplified version of the entanglement-swapping protocol, commonly used in the deployment of quantum networks, is presented. Quantum repeaters are essential in extending the range of quantum networks, especially when they are implemented through the laying of optical fiber. The simplified version of the entanglement-swapping protocol does not require the use of unitary transforms to finish characterizing the shared Bell state at both ends to be connected, as happens in the traditional version of the protocol, facilitating and reducing costs in quantum repeater implementations. Both a theoretical demonstration and an experimental one on an optical table, based on two revealing experiments, show the excellent performance of the presented protocol.
