Circuit Complexity From Cosmological Islands
Sayantan Choudhury, Satyaki Chowdhury, Nitin Gupta +6
Recently in various theoretical works, path-breaking progress has been made in recovering the well-known Page Curve of an evaporating black hole with Quantum Extremal Islands, prop…
QMetrology from QCosmology: Study with Entangled Two Qubit Open Quantum System in De Sitter Space
Sayantan Choudhury, Satyaki Chowdhury, Nitin Gupta +1
In this paper, our prime objective is to apply the techniques of parameter estimation theory and the concept of Quantum Metrology in the form of Fisher Information to investigate t…
Indirect detection of Cosmological Constant from interacting open quantum system
Subhashish Banerjee, Sayantan Choudhury, Satyaki Chowdhury +4
We study the indirect detection of Cosmological Constant from an open quantum system of interacting spins, weakly interacting with a thermal bath, a massless scalar field minimally…
