Distribution of Bell inequality violation vs. multiparty quantum correlation measures
Kunal Sharma, Tamoghna Das, Aditi Sen De +1
Violation of a Bell inequality guarantees the existence of quantum correlations in a quantum state. A pure bipartite quantum state, having nonvanishing quantum correlation, always…
Statistics of leading digits leads to unification of quantum correlations
Titas Chanda, Tamoghna Das, Debasis Sadhukhan +3
We show that the frequency distribution of the first significant digits of the numbers in the data sets generated from a large class of measures of quantum correlations, which are…
Generalized Geometric Measure of Entanglement for Multiparty Mixed States
Tamoghna Das, Sudipto Singha Roy, Shrobona Bagchi +3
Computing entanglement of an arbitrary bipartite or multipartite mixed state is in general not an easy task as it usually involves complex optimization. Here we show that exploitin…
Subtraction better than addition: Entanglement in multimode squeezed vacuum post-interface with photons
Tamoghna Das, R. Prabhu, Aditi Sen De +1
We investigate the entanglement patterns of photon-added and -subtracted four-mode squeezed vacuum states. Entanglements in different scenarios are analyzed by varying the number o…
Reducing Computational Complexity of Quantum Correlations
Titas Chanda, Tamoghna Das, Debasis Sadhukhan +3
We address the issue of reducing the resource required to compute information-theoretic quantum correlation measures like quantum discord and quantum work deficit in two qubits and…
