Local passivity and entanglement in shared quantum batteries
Kornikar Sen, Ujjwal Sen
We identify the conditions for local passivity for shared quantum batteries with local Hamiltonians. For locally passive states of two-qubit batteries, we find the relation of thei…

Beating detection loophole in nonlinear entanglement witnesses
Kornikar Sen, Sreetama Das, Ujjwal Sen
Detectors in the laboratory are often unlike their ideal theoretical cousins. They have non-ideal efficiencies, which may then lead to non-trivial implications. We show how it is p…
