Role of complementary correlations in the evolution of classical and quantum correlations under Markovian decoherence
Prasenjit Deb, Manik Banik
Quantum correlation lies at the very heart of almost all the non-classical phenomena exhibited by quantum systems composed of more than one subsystem. In the recent days it has bee…
Wigner-Yanase skew information and entanglement generation in quantum measurement
Manik Banik, Prasenjit Deb, Samyadeb Bhattacharya
The first step of quantum measurement procedure is known as \emph{premeasurement}, during when correlation between measuring system and measurement apparatus is established. One co…
Several foundational and information theoretic implications of Bell's theorem
Guruprasad Kar, Manik Banik
In 1935, Albert Einstein and two colleagues, Boris Podolsky and Nathan Rosen (EPR) developed a thought experiment to demonstrate what they felt was a lack of completeness in quantu…
Device independent Schmidt rank witness by using Hardy paradox
Amit Mukherjee, Arup Roy, Some Sankar Bhattacharya +3
Schmidt rank of bipartite pure state serves as a testimony of entanglement. It is a monotone under local operation + classical communications (LOCC) and puts restrictions in LOCC c…
Certifiable randomness from temporal correlations
Shiladitya Mal, Manik Banik, Sujit K Choudhary
Leggett-Garg inequalities (LGI) are constrains on certain combinations of temporal correlations obtained by measuring one and the same system at two different instants of time. The…
Measurement-device-independent randomness from local entangled states
Anubhav Chaturvedi, Manik Banik
Nonlocal correlations are useful for device independent (DI) randomness certification [Nature (London) {\bf 464}, 1021 (2010)]. The advantage of this DI protocol over the conventio…
