Researchers have developed the first megapixel photon-counting camera based on new-generation image sensor technology that uses single-photon avalanche diodes (SPADs). The new camera can detect single photons of light at unprecedented speeds, a capability that could advance applications that require fast acquisition of 3D images such as augmented reality and LiDAR systems for autonomous vehicles.

“Thanks to its high resolution and ability to measure depth, this new camera could make virtual reality more realistic and let...

An international team of researchers have found a new way to speed up quantum computing that could pave the way for huge leaps forward in computer processing power. Scientists from the University of Nottingham and University of Stockholm have sped-up trapped ion quantum computing using a new experimental approach – trapped Rydberg ions; their results have just been published in Nature.

In conventional digital computers, logic gates consist of operational bits that are silicon based electronic devices. Information is encoded in two classical states (“0” and “1”) of a bit. This means that capacities of a classical computer increase linearly with the number of bits. To deal with emerging scientific and industrial problems, large computing facilities or supercomputers are built.

Novel plate-cell architecture reaches theoretical limit of performance. Researchers at the University of California, Irvine and other institutions have architecturally designed plate-nanolattices — nanometer-sized carbon structures — that are stronger than diamonds as a ratio of strength to density.

In a recent study in Nature Communications, the scientists report success in conceptualizing and fabricating the material, which consists of closely connected, closed-cell...

New research finds that magnetic wires, spaced a certain way, can lead to a 20-30x reduction in the amount of energy needed to run neural network training algorithms.

The rapid progression of technology has led to a huge increase in energy usage to process the massive troves of data generated by devices. But researchers in the Cockrell School of Engineering at The University of Texas at Austin have found a way to make the new generation of smart computers more energy efficient.

Traditionally, silicon chips have formed the building blocks of the infrastructure that powers computers...
