- Abstract summary: Quantum correlations that typically develop between a quantum battery and its charger reduce the amount of work extractable from the battery.<n>We show that by coupling the system with an additional environment that can be continuously monitored, one can weaken these correlations and enhance work extraction beyond what is achievable in the ideal (closed system) limit.

- Abstract: Quantum correlations that typically develop between a quantum battery and its charger reduce the amount of work extractable from the battery. We show that by coupling the system with an additional environment that can be continuously monitored, one can weaken these correlations and enhance work extraction beyond what is achievable in the ideal (closed system) limit. This general mechanism is illustrated using both a cavity-mediated spin-spin and Dicke quantum battery models.
