Stable Long-Range Charging and Boundary-Mediated Thresholds in a Waveguide Quantum Battery
Abstract
The waveguide-integrated architecture holds promise for scalable on-chip integration of a charger, a transmission channel, and a quantum battery in a modular, independently optimizable design. We investigate a minimal charging configuration consisting of two emitters coupled to a semi-infinite waveguide and identify the optimal charging mechanism, wherein non-Markovian dynamics driven by out-of-band bound states give rise to single-frequency oscillations of the stored energy. We show that near-unity charging efficiency is achievable at weak to moderate coupling strengths via detuning control, provided that the battery-to-boundary separation n is less than three times the charger-to-boundary separation m (n<3m)---a constraint imposed by the mirror-induced feedback---while the average charging power decays exponentially with the spatial separation n−m. These findings offer useful insights for monolithic solid-state quantum energy storage and transport.
