Scientists have achieved a breakthrough in analog computing, developing a programmable electronic circuit that harnesses the properties of high-frequency electromagnetic waves to perform complex parallel processing at light-speed.

The discovery points to a new era of computing that operates far beyond the limits of conventional digital electronics, using less energy, while performing massive calculations.

The study, “Programmable circuits for analog matrix computations,” has been published in Nature Communications.

The research was led by Dr...
