Every electronic device - from a supercomputer to a dishwasher - works by controlling the flow of charged electrons . But electrons can carry so much more information than just charge ; electrons also spin , like a gyroscope on axis .
Harnessing electron spin is really exciting for quantum information processing because not only can an electron spin up or down -one or zero -but it can also spin any direction between

The ability to manipulate electrons in a conducting material like light rays opens up entirely new ways of thinking about electronics . The switches that make up computer chips operate by turning the entire device on or off , and this consumes significant power .

The melting of electrons . In the blue areas , the electrons ( red dots ) are stuck to the atoms in the lattice ( green circles ), meaning that there is no current . In the red areas , dopant atoms ( black circles ) are added , giving the electrons room to move and making them behave like a liquid . The researchers expect that once the whole area is molten , the material is a high-temperature |
example in electronic devices and computer memory . Current ferroelectric materials are highly valued for their thermal and chemical stability and rapid electro-mechanical responses , but creating a material that is scalable down to the tiny sizes needed for technologies like silicon-based semiconductors ( Si-based
CMOS ) has proven challenging .
