Scientists have made a breakthrough in the development of a new generation of electronics that will require less power and generate less heat.

It involves exploiting the complex quantum properties of electrons—in this case, the of electrons.

In a world first, the researchers—led by a team of physicists from the University of Leeds—have announced in the journal Science Advances that they have created a 'spin capacitor' that is able to generate and hold the spin state of electrons for a number of hours.

Previous attempts have only ever held the spin state for a fraction of a second.
