Two-photon parametric amplification in a superconducting circuit exponentially strengthens cavity-qubit coupling, enabling faster charging and decoherence-resistant energy storage in a quantum battery.
Defines isoergotropic states and ergotropy-preserving operations that redistribute coherent-incoherent or displacement-squeezing components in quantum batteries without changing total ergotropy.
Squeezing-induced symmetry breaking exponentially amplifies nonreciprocity in cavity-reservoir systems, boosting quantum battery metrics and optical isolation by orders of magnitude.
