Photonic deep neural network chip Engineers from the University of Pennsylvania built a photonic deep neural network on a 9.3 square millimeter chip they say is faster and more efficient at classifying images, with the ability to process nearly two billion images a second. The chip uses a series of waveguides that form 'neutron layers' mimicking the brain. “Our chip processes information ... » read more

Chiplets Enter The Supercomputer Race
By Mark LaPedus - 17 Mar, 2022 - Comments: 0

Several entities from various nations are racing each other to deliver and deploy chiplet-based exascale supercomputers, a new class of systems that are 1,000x faster than today’s supercomputers. The latest exascale supercomputer CPU and GPU designs mix and match complex dies in advanced packages, adding a new level of flexibility and customization for supercomputers. For years, various na... » read more

Measuring microdroplets The National Institute of Standards and Technology (NIST) has found a new way for microscopes to measure the volumes of microdroplets. Using this technique, NIST has measured the volume of individual droplets smaller than 100 trillionths of a liter with an uncertainty of less than 1%. That represents a tenfold improvement compared to previous measurements, according ... » read more

The Great Quantum Computing Race
By Mark LaPedus - 26 Jul, 2021 - Comments: 0

Quantum computing is heating up, as a growing number of entities race to benchmark, stabilize, and ultimately commercialize this technology. As of July 2021, a group from China appears to have taken the lead in terms of raw performance, but Google, IBM, Intel and other quantum computer developers aren’t far behind. All of that could change overnight, though. At this point, it's too early t... » read more

Graphene energy Researchers from the University of Arkansas, University of Pennsylvania, and Universidad Carlos III de Madrid built a circuit capable of capturing graphene's thermal motion and converting it into an electrical current. "An energy-harvesting circuit based on graphene could be incorporated into a chip to provide clean, limitless, low-voltage power for small devices or sensors,... » read more

Up-converting lasers Researchers at the University of Pennsylvania developed a filter chip that can convert the output from low-cost lasers to have the same frequency noise as big, expensive lasers, making them suitable for applications such as LiDAR. The noise in a laser's frequency is an important indicator of quality. Low-quality, noisy lasers have more random variations, making them use... » read more

One-directional optical Researchers from University of Pennsylvania, Peking University and Massachusetts Institute of Technology developed a design for optical devices that radiate light in only one direction, which could reduce energy consumption in optical fiber networks and data centers. Light tends to flow in a single direction optical fibers, but while most of the light passing through... » read more

Warmer quantum computing Researchers at the University of New South Wales Sydney, Université de Sherbrooke, Aalto University, and Keio University developed a proof-of-concept quantum processor unit cell on a silicon chip that works at 1.5 Kelvin – 15 times warmer than current chip-based technology that uses superconducting qubits. "This is still very cold, but is a temperature that can b... » read more

Week In Review: Auto, Security, Pervasive Computing
By SE Staff - 15 May, 2020 - Comments: 0

Security Ninety-one percent of commercial applications contain outdated or abandoned open-source components —a security threat, says Synopsys in its recently released report 2020 Open Source Security and Risk Analysis (OSSRA). In the fifth annual edition of the report, Synopsys’ research team in its Cybersecurity Research Center (CyRC) found that 99% of the 1,250 commercial codebases revie... » read more

Complex microparticles A team of researchers have developed the world’s most complex microparticle. In the lab, researchers have assembled hierarchically organized particles with twisted spikes and polydisperse Au-Cys (gold-cysteine) nanoplatelets or nanosheets. The sheets all twist in the same direction. Cysteine is a proteinogenic amino acid. The structure is said to be more complex ... » read more
