“…with r ij and r ij are form equations ( 42)- (43). As in the previous section, we can see equation (51) as a statistical mixture of local noise case (section 3.3) with probability (1 − η) and a maximally mixed state case with probability η.…”

“…They investigated the effectiveness of quantum teleportation by analytically solving a master equation in Lindblad form. Similar evaluations were carried out in other schemes [39][40][41][42][43][44][45]. In all of the noisy teleportation evaluations mentioned above, noise is assumed to exist only when the channel is distributed to the parties.…”

An asymmetric bidirectional quantum controlled teleportation via a seven-qubit Werner-like mixed state is proposed. In the process of teleportation preparation, it is hypothesized that three imperfections could appear, namely (i) imperfection of the entangler device that may result in a non-maximal entanglement of the channel, (ii) local noises are introduced during the channel preparation process, and (iii) global noises occur during the channel state distribution to the corresponding parties. The local and global noises are selected as depolarizing noise with certain probability of transforming any entangled state into a maximally mixed state, resulting in a seven-qubit Werner-like mixed state. The teleportation fidelity with the presence of the imperfections is evaluated. It is shown that the teleportation is more robust under the presence of global noise compared to local noise.

“…QT is a quantum information transmission method based on communicating quantum states by using classical resources and multi-qubit entangled states as the quantum channel [13][14][15]. Historically, QT was first introduced by Bennet et al [16] in 1993 using the Bell states to send an arbitrary single-qubit state.…”

“…Moreover, it is worth noting that designing cyclic QT protocols can be more practical and reliable based on classical communication systems, but it could also be beneficial for distributed quantum systems and quantum nodes between the linked big data processors [26]. Nowadays, along with expanding the speed and volume of communication systems, we are witnessing the exponential growth in demands for ultra-high private and secure communication systems due to the significant importance of data protection and privacy [27]. So, due to this trend in the growth and hierarchy of classical communication technology, designing ultra-high secure QT protocols is a mandatory approach.…”

This paper proposes an asymmetric tridirectional quantum teleportation (TQT) protocol that uses a seven-qubit cluster states as the quantum channels of each party. In this scheme, any one of the three participants can send their arbitrarily entangled states to the other two concurrently. The tridirectional functionality shows that all three users can act as sender and receiver simultaneously. Based on the mathematical modeling of the scheme, the quantum circuit and the appropriate quantum channel is proposed. For examination and implementation, the proposed scheme and circuit were simulated and validated using IBM quantum experience platform, QASM_simulator and Qiskit library.

“…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.
