Maximally Sliced States as a Framework for Quantum Coherence, Entanglement, and Teleportation under Decoherence
Anushree Pandey, Sovik Roy
Quantum resources such as coherence and entanglement need not exhibit the same dependence on the parameters of a quantum state, and their responses to decoherence can differ qualit…
Non-maximally entangled mixed states of X and non-X types as teleportation channels
Anushree Pandey, Sovik Roy, Md. Manirul Ali +1
Mixed spin-1/2 states violating Bell-CHSH inequality is useful for teleportation. There exist states which do not violate Bell-inequality but is still useful as teleportation chann…
Entanglement preservation in tripartite quantum systems under dephasing dynamics
Chandrashekar Radhakrishnan, Sovik Roy, Ravikumar Chinnarasu +1
Protecting entanglement from decoherence is a critical aspect of quantum information processsing. For many-body quantum systems evolving under decoherence, estimating multipartite…
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…
Study on Entanglement and its Utility in Information Processing
Sovik Roy
The efficacies of maximally and that of non-maximally entangled mixed states as teleportation channels have been studied. A new class of non-maximally entangled mixed states have b…
Detecting Einstein-Podolsky-Rosen steering through entanglement detection
Debarshi Das, Souradeep Sasmal, Sovik Roy
Quantum inseparabilities can be classified into three inequivalent forms: entanglement, Einstein-Podolsky-Rosen (EPR) steering, and Bell's nonlocality. Bell-nonlocal states form a…
