Entanglement Makes Quantum Batteries Almost Perfect, Say Theorists | MIT Technology Review

Entanglement Makes Quantum Batteries Almost Perfect, Say Theorists | MIT Technology Review: Alicki and Fannes show that when quantum batteries are entangled they become much better. That’s essentially because all the energy from all the batteries can be extracted at once...
In fact, as the number of entangled batteries increases, the performance becomes arbitrarily close to the thermodynamic limit...
...Quantum batteries in the form of atoms or molecules may be ubiquitous in nature, in processes such as photosynthesis. Biologists know for example that during photosynthesis, energy is transferred with 100 per cent efficiency from one molecular machine to another.
How this happens, nobody knows.
