MIT researchers have designed a way to generate, at room temperature, more single photons for carrying quantum information. The design, they say, holds promise for the development of practical quantum computers. Quantum emitters generate photons that can be detected one at a time. Consumer quantum computers and devices could potentially leverage certain properties of those photons as…

Computing Faster With Quasi-particles
Majorana particles are very peculiar members of the family of elementary particles. First predicted in 1937 by the Italian physicist Ettore Majorana, these particles belong to the group of so-called fermions, a group that also includes electrons, neutrons and protons. Majorana fermions are electrically neutral and also their own anti-particles. These exotic particles can, for…
Researchers Take a Step Toward Light-based, Brain-like Computing Chip
A technology that functions like a brain? In these times of artificial intelligence, this no longer seems so far-fetched—for example, when a mobile phone can recognize faces or languages. With more complex applications, however, computers still quickly come up against their own limitations. One of the reasons for this is that a computer traditionally has…

The Power of Randomization: Magnetic Skyrmions for Novel Computer Technology
Researchers at Johannes Gutenberg University Mainz (JGU) have succeeded in developing a key constituent of a novel unconventional computing concept. This constituent employs the same magnetic structures that are being researched in connection with storing electronic data on shift registers known as racetracks. In this, researchers investigate so-called skyrmions, which are magnetic vortex-like structures, as…

Berkeley Lab Highlights ‘the Little Computer Cluster That Could’
Decades before “big data” and “the cloud” were a part of our everyday lives and conversations, a custom computer cluster based at the Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab) enabled physicists around the world to remotely and simultaneously analyze and visualize data. The Parallel Distributed Systems Facility (PDSF) cluster, which had served…
Computer Model Suggests Earthquakes Are Triggered Well Beyond Fluid Injection Zones
Using data from field experiments and modeling of ground faults, researchers at Tufts University have discovered that the practice of subsurface fluid injection used in “fracking” and wastewater disposal for oil and gas exploration could cause significant, rapidly spreading earthquake activity beyond the fluid diffusion zone. Deep fluid injections—greater than one kilometer deep—are known to…
Promising Material Could Lead to Faster, Cheaper Computer Memory
Computer memory could become faster and cheaper thanks to research into a promising class of materials by University of Arkansas physicists. The scientists are studying bismuth ferrite, commonly abbreviated as BFO, a material that has the potential to store information much more efficiently than is currently possible. BFO could also be used in sensors, transducers…
