Study reveals quantum limits on battery reliability and power

Researchers have identified fundamental limits to the reliability and power stability of quantum batteries, according to a new theoretical study. The work shows that it's impossible to minimize fluctuations in both delivered energy and power at the same time due to quantum uncertainty. The findings suggest strategies that balance power and stability, but highlight challenges for making quantum batteries practical energy sources.

• Quantum uncertainty limits battery energy and power stability
• Collective charging boosts power but increases fluctuations
• Group-based charging balances power and stability
• Study sets expectations for future quantum battery designs
