Quantum battery optimized by parametric amplification

Fang-Mei Yang, Fu-Quan Dou, Jun-Hong An

Two-photon parametric driving exponentially strengthens cavity-qubit coupling in a superconducting circuit, producing entangled states that speed energy transfer into a quantum battery while suppressing decoherence.

The bundle contains the canonical record plus signed events. A mirror can host it anywhere and recompute the same current state with the deterministic merge algorithm.

Claims

C1strongest claim

two-photon parametric driving exponentially enhances the effective cavity-qubit coupling, which in turn gives rise to near-degenerate energy-level structures and highly entangled quantum states. This significantly enhances the charging power and enables rapid energy transfer from the charger to the battery.

C2weakest assumption

That the two-photon driving term can be realized in the superconducting circuit without introducing uncontrolled higher-order nonlinearities or excess noise that would invalidate the exponential enhancement and decoherence suppression claims.

C3one line summary

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.
