Conclusive Identification of Quantum Channels via Monogamy of Quantum Correlations
Asutosh Kumar, Sudipto Singha Roy, Amit Kumar Pal +3
We investigate the action of local and global noise on monogamy of quantum correlations, when monogamy scores are considered as observables, and three-qubit systems are subjected t…
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…
Dual quantum-correlation paradigms exhibit opposite statistical-mechanical properties
R. Prabhu, Aditi Sen De, Ujjwal Sen
We report opposite statistical mechanical behaviors of the two major paradigms in which quantum correlation measures are defined, viz., the entanglement-separability paradigm and t…
Conditions for Monogamy of Quantum Discord: Greenberger-Horne-Zeilinger versus W states
R. Prabhu, Arun Kumar Pati, Aditi Sen De +1
Quantum correlations are expected to respect all the conditions required for them to be good measures of quantumness in the bipartite scenario. In a multipartite setting, sharing e…
Disorder overtakes Order in Information Concentration over Quantum Networks
R. Prabhu, Saurabh Pradhan, Aditi Sen De +1
We consider different classes of quenched disordered quantum XY spin chains, including quantum XY spin glass and quantum XY model with a random transverse field, and investigate th…
