Quantum batteries harnesses the power of 'indefinite causal order'

https://phys.org/news/2023-12-batteries-harnesses-power-indefinite-causal.html

"composed of microscopic particles like arrays of atoms which are quantum... charge using optics and indefinite causal order (ICO) quantum effect allowing superposition enabling charging more energetic battery with significantly less power... more energy stored and thermal efficiency... lower-power charger provide higher energies with greater efficiency than comparably higher-power charger using same apparatus (inverse interaction effect)... solar panels with reduced degradation from heat, EVs, smartphones"
