Achieving Identical Stored Energy in Cascaded Collisional Quantum Battery Charging: Analytical Result
The study developed an adaptive-angle measurement protocol for cascaded collision models in quantum battery charging. By dynamically tuning the measurement basis of a charger after each collision, the researchers achieved complete suppression of stored-energy fluctuations when chargers are excited. For superposition-state chargers, this method substantially reduces these fluctuations compared to fixed measurements.
