This research demonstrates a novel polymorphic architecture for superconducting circuits where quantum resource generation and energy storage occur simultaneously within the same hardware dynamics. By allowing experimental runs to interchangeably function as either quantum batteries or sensors, this approach eliminates redundant infrastructure costs while advancing dual-use capabilities in quantum platforms.
Dual-use quantum hardware for quantum resource generation and energy storage
arXiv:2604.21913v3 Announce Type: replace Abstract: Efficient generation of quantum resources is a central objective of modern quantum technological platforms. Independently, quantum batteries have emerged as nanoscale devices that utilize collective quantum effects to store energy with a charging advantage over classical strategies. Here, we show a direct connection between these two pursuits: protocols for fast generation of resourceful quantum states can simultaneously charge a quantum battery with a collective advantage, and conversely, a quantum battery protocol with a charging advantage rapidly produces resource-rich states. Using this connection, we propose an integrated hardware protocol on superconducting circuits in which each experimental run can interchangeably accomplish either quantum battery charging, or quantum sensing through generation of metrologically useful states. Our results establish that quantum resources and stored energy are distinct yet simultaneously-producible quantities within the same dynamics. This opens the door to polymorphic quantum architectures that dynamically switch between sensing and energy-storage functions, thereby producing additional functionalities without extra hardware cost.
