In this paper, we present a quantum key agreement (QKA) protocol with non-maximally
entangled four-qubit cluster states. In our scheme, each participant carries out two unitary …

Traditional classical internet facilitates the sharing of classical information between
computers and devices serving as nodes while'to be evolved'Quantum-Internet would be …

Coupling to the environment typically suppresses quantum properties of physical systems
via decoherence mechanisms. This is one of the main obstacles in practical …

We study bidirectional teleportation while explicitly taking into account a mixed environment.
This environment initially causes pure dephasing decoherence of the Bell state which …

Very recently, Lee et al. proposed a secure quantum teleportation protocol to transfer shared
quantum secret between multiple parties in a network [Phys. Rev. Lett. 124 060501 (2020)] …

In this paper, by utilizing a nine-qubit entangled state as a quantum channel, we propose
new schemes for symmetric and asymmetric cyclic controlled quantum teleportation …

We investigate the effect of noise on a class of four-qubit entangled channels for two-qubit
teleportation from Alice to Bob. These entangled channels include both parallel Bell pairs …

In this paper, we propose a new scheme for faithful bidirectional quantum teleportation
(BQT) of special type of two-qubit entangled states by using single G state as a quantum …

We investigate the intricate dynamics of quantum coherence and non-classical correlations
in a two-qubit open quantum system coupled to a squeezed thermal reservoir. By exploring …

A four-party single-qubit operation sharing scheme is put forward by utilizing the Bell and
Yeo–Chua product state in an entanglement structure as the composite quantum channel …
