“…The speciality of the noisy environment considered here is that all the qubits which are transmitted experience noise individually, that is, there is no correlation regarding the noisy environment between two qubits even when they are sent to the same party in the same prevalent noisy environment. This is reflected in the expression of equation (7) where the ' ' is over the indices l, m and n. It is known that there are other types of noises than those considered here which can be modeled using the Kraus operator. There is no intrinsic reason for our consideration of only these three types of representative noises.…”

“…It is a technique for transfer of unknown quantum information from one location to a distant location through a previously shared entanglement between the sender and the receiver. Since then, a series of modified quantum teleportation protocols such as controlled teleportation [2][3][4][5][6][7][8][9], bi-directional teleportation [10][11][12][13][14][15][16], probabilistic teleportation [17][18][19][20][21][22], cyclic teleportation [23][24][25][26][27][28], multi-hop teleportation [29][30][31][32][33] and so on were developed in course of the last three decades which are applicable to a very wide variety of quantum states.…”

In this paper we discuss a quantum multi-tasking protocol for preparation of known one-qubit and two-qubit states respectively in two different locations. The ideal remote state preparation protocol is discussed in the first place in which a five-qubit entangled state is utilized. The design for the preparation of such entanglement is also presented and run on IBM quantum composer platform. The effects of three types of noises on the protocol are discussed and in all these cases the reduced fidelities of the process are calculated. The variations of these fidelities with respect to different parameters are analysed.

“…Since then, many different QT schemes have been proposed with noisy channels. [32][33][34][35] Researchers have analyzed the effects of different types of noise on teleportation by calculating the fidelity of teleportation. A variety of techniques have been used to improve fidelity, such as entanglement distillation and weak measurement.…”

This paper proposes a three-dimensional (3D) controlled quantum teleportation scheme for an unknown single-qutrit state. The scheme is first introduced in an ideal environment, and its detailed implementation is described via the transformation of the quantum system. Four types of 3D-Pauli-like noise corresponding to Weyl operators are created by Kraus operators: trit-flip, t-phase-flip, trit-phase-flip, and t-depolarizing. Then, this scheme is analyzed in terms of four types of noisy channel with memory. For each type of noise, the average fidelity is calculated as a function of memory and noise parameters, which is afterwards compared with classical fidelity. The results demonstrate that for trit-flip and t-depolarizing noises, memory will increase the average fidelity regardless of the noise parameter. However, for t-phase-flip and trit-phase-flip noises, memory may become ineffective in increasing the average fidelity above a certain noise threshold.

“…In addition, many improved QT schemes have been proposed, such as quantum information splitting (QIS) [15]- [17], quantum secret sharing (QSS) [18]- [20], controlled quantum teleportation (CQT) [21]- [23] and bidirectional quantum teleportation (BQT) [24]- [31], [33]- [40] and so on, which all can be considered as the expansion of QT. Among these, the BQT is such a scheme that the sender and receiver can realize the mutual transmission of quantum state information by using multi-qubit entangled states as quantum channels.…”

In this paper, a theoretical scheme for bidirectional quantum teleportation by using a four-qubit GHZ state and two Bell states as a quantum channel is proposed. In this scheme, two arbitrary single-qubit quantum states and an unknown three-qubit state can be mutually transmitted between the two communication participants Alice and Bob. The quantum state information can be transmitted if Alice performs four single-qubit measurement operations on her qubits and Bob carries out a four-qubit joint measurement on his qubits, respectively. Then both Alice and Bob can reconstruct the target quantum state by means of appropriate unitary operations. Then we take comparisons with the other bidirectional quantum teleportation protocols in five aspects of quantum information bits transmitted, necessary operations, consumption of quantum resource, consumption of classical resource and intrinsic efficiency. Furthermore, we use channel authentication method to ensure the channel security and prove that our protocol can withstand four attack scenarios. It is concluded that our scheme has significant advantages of more qubits number transmitted, higher intrinsic efficiency and high security. INDEX TERMS Bidirectional quantum teleportation, four-qubit GHZ state and two Bell states, single-qubit measurement, four-qubit joint measurement, channel authentication.
