“…Implementation of the configuration of Figure 7(c) in the Quirk simulator [36]. Both metrics, i.e., the boxes On/Off, and the Bloch's spheres, demonstrate that the CBS to be transmitted and entering the protocol via qubits q[0] to q [3] in the upper left of the figure, are the same recovered in the lower right margin of the same in the qubits q [4] to q [7].…”

“…FIGURE 11 Multi-qubit teleportation protocol. Four qubits q[0]q[1]q [2]q [3] enter to be teleported through the upper left margin of the protocol, which goes to Alice's cascade splitting module (pink) and is subsequently intercepted by the measurement blocks, which transport the results of these measurements to the classic disambiguation channel (gray). In the center-left, an entangled pair is generated, which is stretched to a 9 GHZ state by the combined action of Alice's and Bob's (blue) cascade splitting modules.…”

“…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.

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.

“…It was shown that the maximization/ minimization of the fidelity of the teleported state depends on the teleported information, the trigger's states of the receiver, and the mediator. Another noise evaluation has also been investigated in [33], showing that the bidirectional teleportation fidelities and the quantum Fisher information depend on the survival amount of entanglement in the quantum channel, on the decoherence factor, and the correlation degree of the decoherence channel. Further studies on quantum teleportation in noisy environment can be found in [34][35][36][37][38].…”

We evaluate a one-way, bidirectional, and cyclic quantum controlled teleportation with two controllers. We show that the controllers' agreement mimics the OR logic gate, i.e., the teleportation succeeds with only one of the controllers' cooperation, and it does not matter which one. This result is generalized to multi-ways quantum controlled teleportation with N controllers. The proposed protocols are evaluated by considering a noisy environment in the form of phase-damping noise and amplitude-damping noise and the dependence of fidelity only on the decoherence rate and the initial state’s amplitude parameter were established. It is interesting to note that for the phase-damping noise case, there are states with perfect fidelity (and the entropy equal to zero) even in a noisy environment. We discuss the novelty of the proposed protocols and highlight that they can be useful if the information to be teleported needs an OR-logic-gate-like controllers’ agreement combination, which cannot be done with other existing protocols.
