New design principles for spin-based quantum materials
A new design criteria for enhancing the spin lifetime of a class of quantum materials could support Internet of Things devices and other resource-intensive technologies.
World's smallest ultrasound detector created
Researchers have developed the world's smallest ultrasound detector. It is based on miniaturized photonic circuits on top of a silicon chip. With a size 100 times smaller than an average human hair, the new detector can visualize features that are much smaller than previously possible, leading to what is known as super-resolution imaging.
New data processing module makes deep neural networks smarter
Artificial intelligence researchers have improved the performance of deep neural networks by combining feature normalization and feature attention modules into a single module that they call attentive normalization. The hybrid module improves the accuracy of the system significantly, while using negligible extra computational power.
Security software for autonomous vehicles
Before autonomous vehicles participate in road traffic, they must demonstrate conclusively that they do not pose a danger to others. New software prevents accidents by predicting different variants of a traffic situation every millisecond.
Engineers improve signal processing for small fiber optic cables
Tiny circuits can go the distance. Researchers have mapped a noise-reducing magneto-optical response that occurs in fiber-optic communications, opening the door for new materials technologies.
Light processing improves robotic sensing, study finds
A team of researchers uncovered how the human brain processes bright and contrasting light, which they say is a key to improving robotic sensing and enabling autonomous agents to team with humans.
New machine learning-assisted method rapidly classifies quantum sources
Engineers have created a new machine learning-assisted method that could make quantum photonic circuit development more efficient by rapidly pre-selecting these solid-state quantum emitters.
Quirky response to magnetism presents quantum physics mystery
Scientists describe the quirky behavior of one such magnetic topological insulator. The new article includes experimental evidence that intrinsic magnetism in the bulk of manganese bismuth telluride (MnBi2Te4) also extends to the electrons on its electrically conductive surface. Such materials could be just right for making qubits, but this one doesn't obey the rules.
Evidence of power: Phasing quantum annealers into experiments from nonequilibrium physics
Scientists have used commercially available quantum annealers, a type of quantum computer, to experimentally probe the validity of an important mechanism from nonequilibrium physics in open quantum systems. The results not only shed light into the extent of applicability of this mechanism and an extension of it, but also showcase how quantum annealers can serve as effective platforms for quantum simulations.
Detailed picture of US bachelor's programs in computing
With the aim of providing a comprehensive look at computing education, the study includes information on enrollments, degree completions, faculty demographics, and faculty salaries.
Designed antiviral proteins inhibit SARS-CoV-2 in the lab
Computer-designed miniproteins have now been shown to protect lab-grown human cells from SARS-CoV-2, the coronavirus that causes COVID-19. The lead antiviral candidate rivals the best-known SARS-CoV-2 monoclonal antibodies in its protective actions. The synthetic antiviral candidates were designed to prevent infection by interfering with the mechanism that coronaviruses use to break into and enter cells.
Artificial intelligence aids gene activation discovery
Scientists have long known that human genes are activated through instructions delivered by the precise order of our DNA. With the aid of artificial intelligence, researchers have solved a long-standing DNA activation code mystery. Their discovery, which they termed the downstream core promoter region (DPR), could eventually be used to control gene activation in biotechnology and biomedical applications.
New method prevents quantum computers from crashing
Quantum information is fragile, which is why quantum computers must be able to correct errors. But what if whole qubits are lost? Researchers are now presenting a method that allows quantum computers to keep going even if they lose some qubits along the way.
Tool transforms world landmark photos into 4D experiences
Using publicly available tourist photos of world landmarks such as the Trevi Fountain in Rome or Top of the Rock in New York City, researchers have developed a method to create maneuverable 3D images that show changes in appearance over time.
Model shows that the speed neurons fire impacts their ability to synchronize
Research has shown for the first time that a computer model can replicate and explain a unique property displayed by a crucial brain cell. Their findings shed light on how groups of neurons can self-organize by synchronizing when they fire fast.
