Researchers at the University of Vienna have made a key breakthrough in a promising new area of computing that could drastically reduce energy consumption. Their invention, called a “magnonic repeater,” solves a major problem in using magnons—tiny disturbances in magnetic materials—to process data. This development, published in Nature Communications, brings us closer to computers that use less power but can perform tasks faster. A magnon is like a ripple in a magnetic material, similar to how waves spread out when you drop a stone into water. Scientists believe these ripples can replace the electrical currents used in today’s computers, leading to more energy-efficient technology.
