Exploring quantum properties of bipartite mixed states under coherent and incoherent basis
Sovik Roy, Anushree Bhattacharjee, Chandrashekar Radhakrishnan +2
Quantum coherence and quantum entanglement are two different manifestations of the superposition principle. In this article we show that the right choice of basis to be used to est…
Operational criterion for controlled dense coding with non-trivial tripartite entangled states
Sovik Roy, Biplab Ghosh, Md. Manirul Ali
In this paper, we provide an operational criterion for controlled dense coding with a general class of three-qubit partially entangled states. A general three-qubit pure entangled…
A Revisit to Non-maximally Entangled Mixed States: Teleportation Witness, Noisy Channel and Discord
Sovik Roy, Biplab Ghosh
We constructed a class of non-maximally entangled mixed states \cite{roy2010} and extensively studied its entanglement properties and also their usefulness as teleportation channel…
Study of controlled dense coding with some discrete tripartite and quadripartite states
Sovik Roy, Biplab Ghosh
The paper presents the detailed study of controlled dense coding scheme for different types of and particle states. It consists of GHZ state, GHZ type states, Maximal Slic…
Teleportation via maximally and non-maximally entangled mixed states
Satyabrata Adhikari, Archan S. Majumdar, Sovik Roy +2
We study the efficacy of two-qubit mixed entangled states as resources for quantum teleportation. We first consider two maximally entangled mixed states, viz., the Werner state\cit…
Control of atomic entanglement by dynamic Stark effect
Biplab Ghosh, A. S. Majumdar, N. Nayak
We study the entanglement properties of two three-level Rydberg atoms passing through a single-mode cavity. The interaction of an atom with the cavity field allows the atom to make…
