Many computer enthusiasts feel the pinch of energy-hungry electronics that generate excessive heat. Scientists around the globe are searching for fresh strategies to push computing performance forward.
Some experts aim to replace moving electrons with something less draining. They are testing a phenomenon known as magnon transport, where magnetic signals carry information instead of electric currents.
One leading figure in this area is Dr. Andrii Chumak at the University of Vienna. His team has created a prototype processor that runs on magnetic excitations rather than typical electronic pulses.
