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…
Light Cone-Like Behavior of Quantum Monogamy Score and Multisite Entanglement
R. Prabhu, Arun Kumar Pati, Aditi Sen De +1
There are two important paradigms for defining quantum correlations in quantum information theory, viz. the information-theoretic and the entanglement-separability ones. We find an…
Locally Accessible Information of Multisite Quantum Ensembles Violates Monogamy
Aditi Sen De, Ujjwal Sen
Locally accessible information is a useful information-theoretic physical quantity of an ensemble of multiparty quantum states. We find it has properties akin to quantum as well as…
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…
Quantum Advantage in Communication Networks
Aditi Sen De, Ujjwal Sen
Quantum channels are known to provide qualitatively better information transfer capacities over their classical counterparts. Examples include quantum cryptography, quantum dense c…
