We studied entropic uncertainty in quantum batteries. Non-Markovian dynamics and entanglement enhance charging power and energy storage, with entropic bound tightness indicating energy transfer efficiency.
Area of Science:
- Quantum physics
- Quantum information science
- Thermodynamics
Background:
- Open quantum batteries (QBs) are crucial for quantum energy storage.
- Understanding charging dynamics in dissipative environments is essential.
- Entropic uncertainty plays a key role in quantum system evolution.
Purpose of the Study:
- To investigate the dynamics of entropic uncertainty during the charging of QBs.
- To explore the influence of Markovian and non-Markovian environments on QB charging.
- To identify key factors affecting energy storage and charging power.
Main Methods:
- Analysis of entropic uncertainty in Markovian and non-Markovian regimes.
- Study of quantum batteries coupled to a common dissipation environment.
- Examination of the role of entanglement and system-reservoir couplings.
Main Results:
- Strong non-Markovian properties significantly improve QB charging power and efficiency.
- Energy storage is enhanced by stronger couplings between the charger-reservoir and battery-reservoir.
- Entanglement is necessary for maximum energy storage and correlates with the least tight entropic bound.
- Entropic bound tightness serves as a reliable indicator of energy transfer efficiency.
Conclusions:
- Non-Markovian dynamics and entanglement are vital for optimizing quantum battery charging.
- System-environment couplings critically influence energy storage capacity.
- The entropic uncertainty bound provides a valuable metric for assessing energy transfer in quantum charging processes.

The relation between entropy and disorder can be illustrated with the example of the phase change of ice to water. In ice, the molecules are located at specific sites giving a solid state, whereas, in a liquid form, these molecules are much freer to move. The molecular arrangement has therefore become more randomized. Although the change in average...
