Scientists have developed a project of a quantum battery that does not lose charge

Researchers have presented a theoretical model of a quantum battery that can work without energy loss.

It is a nanoscale device designed for use in equipment based on quantum technologies.According to scientists from the Universities of Alberta and Toronto, though, unlikeIn practice , it can be made of modern solid materials.

In the course of the study, the team looked at a modelopen quantum network with high structural symmetry as a platform for storage of exciton energy. Scientists have shown that the charge can be stored without loss even in an open system.

To do this, a quantum network must be prepared incalled the dark state, when it cannot exchange energy with the environment. This makes such a system immune to any external influences, preventing the loss of energy.

Using this model, the researchers proposed a general method for discharging the energy stored in a quantum battery on demand, by means of controlled breaking of the structural symmetry of the network.

In the future, the group will study practical methods of charging and discharging, as well as methods for scaling the device for real applications.

Recently, physicists have successfully transmitted quantum entanglement between matter and light over a distance of 50 km using a fiber-optic cable, which opens upThe path to long-distance quantum networks.
