We generalized the maximally entangled Hamiltonian of the isotropic Heisenberg XX model with two spin-1/2 particles to the case of non-maximal entanglement parametrized by the degree of non-maximality 0 < n < 1. The thermal concurrence as the function of the degree of non-maximality in the entanglement at different values of the exchange parameter is calculated. We analyzed the efficiencyof the quantum Otto engine for different scenarios of exchange parameter regimes and the degree of maximal entanglement between the spin states. We showed that it is possible to run the quantum Otto engine using non-maximally entangled states and achieve higher efficiencies by controlling the exchange parameter value with respect to a critical value Jc and this feature also depends on the degree of non-maximal entanglement n 6= 1. This result may be useful for harnessing the non-maximal entanglement in quantum heat engine for optimizing the operation of quantum devices interacting with heat bath or environment.

“…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.

“…Later, in 2013, they formally named this mode of quantum communication as bidirectional controlled quantum state teleportation (BCQST) [26]. Due to its immense potential application value, BCQST has attracted much interests [27][28][29][30][31][32][33][34][35][36] so far.…”

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

et al. 2022

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.
