In a potential boost for quantum computing and communication, a European research collaboration reported a new method of controlling and manipulating single photons without generating heat. The solution makes it possible to integrate optical switches and single-photon detectors in a single chip.
Inspired by the eyes of mantis shrimp, researchers have developed a new kind of optical sensor that is small enough to fit on a smartphone but is capable of hyperspectral and polarimetric imaging.
Every aspect of modern computing, from the smallest chip to the largest data center comes with a carbon price tag. The tech industry and the field of computation as a whole have focused on building smaller, faster, more powerful devices -- but few have considered their overall environmental impact. SEAS researchers are trying to change that by challenging the field to add carbon footprint to the list of metrics when designing new processes, new computing systems, new hardware, and new ways to use devices.
When quantum computers become more powerful and widespread, they will need a robust quantum internet to communicate. Purdue University engineers have addressed an issue barring the development of quantum networks that are big enough to reliably support more than a handful of users.
Multiscale coarse-grained model of complete SARS-CoV-2 virion developed for first time using supercomputers. Cooperative motion of coronavirus spike protein simulations likely informative of how virus explores and detects ACE2 receptors of potential host cell. Frontera supercomputer at TACC generated all-atom simulations of coronavirus spike protein system that fed into coarse-grained model. Whole coronavirus model provides iterative platform useful for design of safer, better medicines to treat and prevent COVID-19.
Graphene is not magnetic -- a shortcoming that has stunted its usefulness in spintronics, an emerging field that could rewrite the rules of electronics, leading to more powerful semiconductors and computers. University at Buffalo researchers report an advancement to overcome this obstacle. In a study published today in Physical Review Letters, researchers describe pairing a magnet with graphene, and inducing what they call "artificial magnetic texture" in the nonmagnetic wonder material.
A new theory by Rice University scientists could boost the growing field of spintronics, a key to creating faster and more powerful electronic devices, including quantum computers.
MIT researchers developed a data transfer link that's slimmer, more energy efficient, and faster than alternatives like USB or fiber optics. The advance could cut energy budgets at data centers and lighten the load for electronics-rich aircraft.
Responding to artificial intelligence's exploding demands on computer networks, Princeton University researchers in recent years have radically increased the speed and slashed the energy use of specialized AI systems. Now, the researchers have moved their innovation closer to widespread use by creating co-designed hardware and software that will allow designers to blend these new types of systems into their applications.
Plants and animals can rapidly respond to changes in their environment, such as a Venus flytrap snapping shut when a fly touches it. However, replicating similar actions in soft robots requires complex mechanics and sensors. Now, researchers reporting in ACS Applied Materials & Interfaces have printed liquid metal circuits onto a single piece of soft polymer, creating an intelligent material that curls under pressure or mechanical strain.
