Viscous attenuation of gravitational waves propagating through an inhomogeneous background
Shashank Shekhar Pandey, Arnab Sarkar, Amna Ali +1
We consider the propagation of gravitational waves in the late-time Universe in the presence of matter distribution inhomogeneities, and we also consider the cosmic fluid to be vis…
Unruh quantum Otto engine in the presence of a reflecting boundary
Arnab Mukherjee, Sunandan Gangopadhyay, A. S. Majumdar
We introduce a new model of relativistic quantum analogue of the classical Otto engine in the presence of a perfectly reflecting boundary. A single qubit acts as the working substa…
Wigner's approach enabled detection of multipartite nonlocality using all different bipartitions
Sumit Nandi, Debashis Saha, Dipankar Home +1
Distinct from Bell's approach, Wigner had derived a form of local realist (LR) inequality which is quantum mechanically violated for a bipartite maximally entangled state. Subseque…
Bell's inequality violation by dynamical Casimir photons in a superconducting microwave circuit
Riddhi Chatterjee, A. S. Majumdar
We study the Bell's inequality violation by dynamical Casimir radiation with pseudospin measurement. We consider a circuit quantum electrodynamical set-up where a relativistically…
Robust certification of arbitrary outcome quantum measurements from temporal correlations
Debarshi Das, Ananda G. Maity, Debashis Saha +1
Certification of quantum devices received from unknown providers is a primary requirement before utilizing the devices for any information processing task. Here, we establish a pro…
Resource theoretic efficacy of the single copy of a two-qubit entangled state in a sequential network
Arun Kumar Das, Debarshi Das, Shiladitya Mal +2
How best one can recycle a given quantum resource, mitigating the various difficulties involved in its preparation and preservation, is of considerable importance for ensuring effi…
