Complete extension: the non-signaling analog of quantum purification
Marek Winczewski, Tamoghna Das, John H. Selby +5
Deriving quantum mechanics from information-theoretic postulates is a recent research direction taken, in part, with the view of finding a beyond-quantum theory; once the postulate…
Response in violation of Bell inequality to imperfect photon addition and subtraction in noisy squeezed states of light
Saptarshi Roy, Titas Chanda, Tamoghna Das +2
Violation of Bell inequality is a prominent detection method for quantum correlations present in composite quantum systems, both in finite and infinite dimensions. We investigate t…
Canonical Leggett-Garg Inequality: Nonclassicality of temporal quantum correlations under energy constraint
Titas Chanda, Tamoghna Das, Shiladitya Mal +2
Nonclassicality of temporal correlations pertaining to noncommutative sequential measurements is defined through the violation of macrorealistic inequalities, known as Leggett-Garg…
How efficient is transport of quantum cargo through multiple highways?
Saptarshi Roy, Tamoghna Das, Debmalya Das +2
Quantum states can be efficiently transferred over a long distance if the entire quantum channel can be divided into several small blocks. We consider a scenario in which each bloc…
