This research demonstrates how continuous environmental monitoring can mitigate detrimental quantum correlations generated during charging, thereby enhancing work extraction in Dicke and cavity-mediated spin-spin battery models beyond closed-system limits. By actively coupling the system to a monitored environment, this study offers a theoretical pathway to improve energy efficiency in future quantum storage architectures without relying on idealized isolation conditions.
Boosting Work Extraction in Quantum Batteries via Continuous Environment Monitoring
arXiv:2512.05244v2 Announce Type: replace Abstract: During the charging process, interactions between a quantum battery and its charger generally generate quantum correlations, which may reduce the amount of work extractable from the battery alone. We show that, by coupling the system with an 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 a Dicke quantum battery model.
