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.

“…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.

“…The generalized Peres-Horodecki criterion relies on the basic differences between classical and quantum covariance/noise matrices [10,11]. One of the advantages of Simon's approach is that it is easy to implement in present-day experimental capacity, in particular, the experimental realization of quantum teleportation of coherent states [12][13][14].…”

Gravitational well is a widely used system for the verification of the quantum weak equivalence principle (WEP). We have studied the quantum gravitational well (GW) under the shed of non-commutative (NC) space so that the results can be utilized for testing the validity of WEP in NC-space. To keep our study widely usable, we have considered both position-position and momentum-momentum non-commutativity. Since coherent state (CS) structure provides a natural bridge between the classical and quantum domain descriptions, the quantum domain validity of purely classical phenomena like free-fall under gravity might be verified with the help of CS. We have constructed CS with the aid of a Lewis-Riesenfeld phase space invariant operator. We deduced the uncertainty relations from the expectation values of the observables and shown that the solutions of the time-dependent Schrödinger equation are squeezed-coherent states.
