In this paper, we propose a novel quantum network coding scheme to achieve the perfect transmission of quantum states without loss of information. In our scheme, two pairs of non-maximally entangled states are pre-shared between senders. By applying the local operations at the sender, the perfect transmission of quantum states can be achieved on th...

We have considered two-qubit Heisenberg XYZ model subject to an external magnetic field in the presence of the Dzyaloshinskii–Moriya (DM) anisotropic antisymmetric interaction as the working substance of the quantum Otto cycle. At first, a scheme is proposed for thermalization where working substance of the quantum Otto cycle is induced in the pres...

The properties of the ferimonic entangled states resulting from the projective measurements in the Gauss–Bonnet spacetime are studied. It is found that the degree of entanglement, for projection onto double particles state, increases monotonously as the Hawking temperature T increases but decreases monotonously as the frequency of the detected part...

The quantum approximate optimization algorithm (QAOA) is a method of approximately solving combinatorial optimization problems. While QAOA is developed to solve a broad class of combinatorial optimization problems, it is not clear which classes of problems are best suited for it. One factor in demonstrating quantum advantage is the relationship bet...

Quantum secure direct communication (QSDC) makes two quantum users transmit secret message directly without first producing a shared secret key. Semi-quantum secure direct communication is a particular case of QSDC when one of the two users is a classical user. How to develop a similar protocol if both users are classical? In this paper, we propose...

The production and manipulation of quantum correlation protocols will play a central role where the quantum nature of the correlation can be used as a resource to yield properties unachievable within a classical framework is a very active and important area of research. In this work, we provide a description of a measure of correlation strength bet...

The quantum teleportation is reexamined in a Fisher information perspective. Two proposals of enhancing the teleportation of quantum Fisher information (QFI) under amplitude damping channel are proposed by utilizing the weak measurement and environment-assisted measurement (EAM), respectively. Although both schemes enable us to improve the teleport...

We develop a new protocol for sharing entanglement (one ebit) between two parties using the natural dynamics of helical multiferroic spin chains. We introduce a novel kicking scheme of the electric field for enhancing the teleportation fidelity in our protocol that works in the presence of an appropriate choice of parameters. We also investigate th...
