# Charging by quantum measurement

@inproceedings{Yan2022ChargingBQ, title={Charging by quantum measurement}, author={Jiazhen Yan and Jun Jing}, year={2022} }

We propose a quantum charging scheme fueled by measurements on ancillary qubits serving as disposable chargers. A stream of identical qubits are sequentially coupled to a quantum battery of N + 1 levels and measured by projective operations after joint unitary evolutions of optimized intervals. If qubit-chargers are prepared in excited state and measured on ground state, their excitations (energy) can be near-completely transferred to battery by iteratively updating the optimized measurement…
