Researchers have developed a revolutionary way to encode computational information without using electrical current. As a global first, this could lead to faster technological devices that could efficiently use energy without overheating.

Modern computer memory encodes information by switching magnetic bits within devices. Now, a ground-breaking study conducted by researchers from the Department of Electrical and Computer Engineering at the National University of Singapore has found a new efficient way of using ‘spin waves’ to switch magnetisation at room temperature for more energy-efficient spin memory and logic devices.

The first ever integrated nanoscale device which can be programmed with either photons or electrons has been developed by scientists in Harish Bhaskaran’s Advanced Nanoscale Engineering research group at the University of Oxford.

In collaboration with researchers at the universities of Münster and Exeter, scientists have created a first-of-a-kind electro-optical device which bridges the fields of optical and electronic computing. This provides an elegant solution to achieving faster and more energy efficient memories and processors.

Computing at the speed of light has been an enticing but elusive prospect, but with this development it’s now in tangible pro...

Scientists have added a crucial tool to the atomic-scale manufacturing toolkit with major implications for today’s data driven—carbon intensive—world, according to new research from the University of Alberta in Canada.

“Computers today are contributing one gigatonne of carbon emissions to the atmosphere, and we can eliminate that by enhancing the most power-hungry parts of conventional computers with our atomic-scale circuitry,” said Robert Wolkow, professor in the University of Alberta’s Department of Physics a Principal Research Officer at the National Research Council of Canada’s Nanotechnology Research Centre, and chief technical officer of Quantum Silicon Inc, a...
