“…Only obtaining the approve and help of the controllers, the receiver can successfully reconstruct the teleported state. Since it can be used as a remote quantum controlled technology, CQT has attracted extensive attentions [42,[57][58][59][60][61][62][63][64][65][66][67][68][69][70] in the past two decades. It should be mentioned that based on a seven-qubit entangled state, Chen et al [67] put forwarded a tripartite CQT scheme (referred to as CLLYZ-CQT scheme hereafter) in which a Bell state can be remotely transmitted under the control of a supervisor.…”

Based on a seven-qubit entangled state, Chen et al (2020 Int. J. Theor. Phys. 59 1402) presented a scheme for controlled quantum teleportation. Using the same quantum channel state, we put forward a new scheme in which the quantum information sender can also transmit a Bell state to receiver under the agreement and assist of the controller. The comparison with Chen et al’s scheme is made and reveals its distinct advantage of reducing the classical resource consumption and increasing the intrinsic efficiency as well as degrading the complexity of necessary operations.

“…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.

“…If and only if with the permission of the controller, the receiver can finally reconstruct the target quantum state. As it can be regarded as a type of quantum remote control, CQST has attracted a large amount of attentions [15][16][17][18][19][20][21][22][23][24].…”

Improving the scheme of bidirectional controlled teleportation with a five-qubit composite GHZ-Bell state

et al. 2022

View full text Add to dashboard Cite

A bidirectional controlled quantum state teleportation (BCQST) scheme was proposed by Li et al (2013 Int. J. Theor. Phys. 52 1630) using a five-qubit composite Greenberger–Horne–Zeilinger-Bell state as the quantum channel. However, it was found to be unsuccessful for bidirectional teleportation control due to its own security loopholes (Shukla et al 2013 Int. J. Theor. Phys. 52 3790). In this paper, we put forward an improved version of the BCQST scheme so that the loopholes are fixed and the bidirectional control can indeed be achieved. In addition, after the improvement, the revised scheme becomes more feasible in terms of present experimental techniques.
