University of Oulu researchers have identified a fundamental trade-off in quantum batteries where minimizing energy fluctuations inevitably increases power instability due to quantum uncertainty. This finding establishes that maximizing charging speed alone is insufficient, necessitating balanced strategies involving intermediate-range interactions to achieve stable operation. These insights are critical for advancing practical quantum energy-storage devices beyond theoretical concepts by addressing inherent constraints from many-body quantum physics.

University of Oulu finds limits on quantum battery power and stability

Quantum ZeitgeistSeptember 28, 20263 min read

University of Oulu research in PRX Quantum reveals limits on both the power and reliable energy delivery of quantum batteries, finding a trade-off due to quantum uncertainty.

University of Oulu researchers have identified a fundamental constraint in quantum battery design, revealing that achieving both stable power and reliable energy delivery is limited by quantum uncertainty. The team’s findings, published in PRX Quantum as “Fundamental Limitations on the Reliabilities of Power and Work in Quantum Batteries,” detail how this trade-off impacts…
