Thermal Fluctuations Enhance Order-from-Disorder of Quantum Correlations in Quenched Disordered Spin Models
Debasis Sadhukhan, R. Prabhu, Aditi Sen De +1
We consider paradigmatic quenched disordered quantum spin models, viz., the XY spin glass and random-field XY models, and show that quenched averaged quantum correlations can exhib…
Distributed quantum dense coding with two receivers in noisy environments
Tamoghna Das, R. Prabhu, Aditi Sen De +1
We investigate the effect of noisy channels in a classical information transfer through a multipartite state which acts as a substrate for the distributed quantum dense coding prot…
To freeze or not to: Quantum correlations under local decoherence
Titas Chanda, Amit Kumar Pal, Anindya Biswas +2
We provide necessary and sufficient conditions for freezing of quantum correlations as measured by quantum discord and quantum work deficit in the case of bipartite as well as mult…
Constructive Interference Between Disordered Couplings Enhances Multiparty Entanglement in Quantum Heisenberg Spin Glass Models
Utkarsh Mishra, Debraj Rakshit, R. Prabhu +2
Disordered systems form one of the centrestages of research in many body sciences and lead to a plethora of interesting phenomena and applications. A paradigmatic disordered system…
Quantum Correlation with Sandwiched Relative Entropies: Advantageous as Order Parameter in Quantum Phase Transitions
Avijit Misra, Anindya Biswas, Arun K. Pati +2
Quantum discord is a measure of quantum correlations beyond the entanglement-separability paradigm. It is conceptualized by using the von Neumann entropy as a measure of disorder.…
Do Large Number of Parties Enforce Monogamy in All Quantum Correlations?
Asutosh Kumar, R. Prabhu, Aditi Sen De +1
Monogamy is a non-classical property that restricts the sharability of quantum correlation among the constituents of a multipartite quantum system. Quantum correlations may satisfy…
