Entangled Measurement Outcomes for Optimal Postselection in Quantum Batteries

arXiv:2610.41121v1 Announce Type: new Abstract: Postselection can enhance the performance of a selected quantum battery branch, raising the question of whether the optimum can always be achieved by product measurements on the auxiliary subsystems. For battery auxiliary states obtained by mixing a pure state with global white noise of strength p, the conditional ergotropy reduces to a generalized Rayleigh quotient.
