Most of us control light all the time without even thinking about it, usually in mundane ways: we don a pair of sunglasses and put on sunscreen, and close—or open—our window blinds. But the control of light can also come in high-tech forms. The screen of the computer, tablet, or phone on which you are reading this is one example. Another is telecommunications, which controls light to create signals that carry data along fiber-optic cables. Scientists also use high-tech methods…
Light offers an irreplaceable way to interact with our universe. It can travel across galactic distances and collide with our atmosphere, creating a shower of particles that tell a story of past astronomical events. Here on earth, controlling light lets us send data from one side of the planet to the other. Given its broad utility, it’s no surprise that light plays a critical role in enabling 21st century quantum information applications. For example, scientists use laser light to precisely control…
Integrated photonics allow us to build compact, portable, low-power chip-scale optical systems used in commercial products, revolutionizing today’s optical datacenters and communications. But integrating on-chip optical gain elements to build lasers or to amplify optical power runs the risk of reflected light from other components compromising or interfering with the laser’s performance. The solution is to increase on-chip optical isolation. Typically, optical isolation is achieved with magnetic materials and magnetic fields, but these are not compatible with current semiconductor foundry…
Scientists from Skoltech, Philips Research, and Goethe University Frankfurt have trained a neural network to detect anomalies in medical images to assist physicians in sifting through countless scans in search of pathologies. Reported in IEEE Access, the new method is adapted to the nature of medical imaging and is more successful in spotting abnormalities than general-purpose solutions. Image anomaly detection is a task that comes up in data analysis in many industries. Medical scans, however, pose a particular challenge. It is way…
New study elucidates fundamental enigma of topological insulators. They are regarded as one of the most interesting materials for future electronics: Topological insulators conduct electricity in a special way and hold the promise of novel circuits and faster mobile communications. Under the leadership of the Helmholtz-Zentrum Dresden-Rossendorf (HZDR), a research team from Germany, Spain and Russia has now unravelled a fundamental property of this new class of materials: How exactly do the electrons in the material respond when they are…
Novel theorem demonstrates convolutional neural networks can always be trained on quantum computers, overcoming threat of ‘barren plateaus’ in optimization problems. Convolutional neural networks running on quantum computers have generated significant buzz for their potential to analyze quantum data better than classical computers can. While a fundamental solvability problem known as “barren plateaus” has limited the application of these neural networks for large data sets, new research overcomes that Achilles heel with a rigorous proof that guarantees scalability. “The way…
Mount Sinai study suggests a new self-learning algorithm may detect blood pumping problems by reading electrocardiograms. A special artificial intelligence (AI)-based computer algorithm created by Mount Sinai researchers was able to learn how to identify subtle changes in electrocardiograms (also known as ECGs or EKGs) to predict whether a patient was experiencing heart failure. “We showed that deep-learning algorithms can recognize blood pumping problems on both sides of the heart from ECG waveform data,” said Benjamin S. Glicksberg, PhD, Assistant…
Laboratory rats have been shown to have genetic consistency and similar responses to drugs with humans, and thus become ideal animal models for research and testing of new drugs. However, due to individual difference, it is still a challenging task to find a method of unified behavior control and evaluation. Actually, bioinspired robots can take advantage of their programmability and reconfigurability to replace rats, so as to effectively solve these problems. It has been verified that robots can influence or…
A plenoptic high-speed camera designed by Fraunhofer researchers. Researchers at Fraunhofer IZM have joined forces with TecVenture, Optrontec Inc., and KAIST to create a high-speed camera fitted with a unique multi-lens array that can capture images with a far greater depth of field than its conventional counterparts. The miniaturized electronics make the system a good choice for efficient damage analytics in industrial use or for many research activities. To prepare the camera for reliable work in the tough reality of…
New information could help improve the reliability of communications. A new data source to help scientists better understand the ionosphere and its potential impact on communications and positioning, navigation, and timing—an essential utility for many critical operations—is now available to the public. The data, which was collected by sensors on GPS satellites in 2018, was released todaythrough a collaborative effort by Los Alamos National Laboratory and the National Oceanic and Atmospheric Administration (NOAA). “Radio signals from satellite or ground-based transmitters can…
In January 2021, Empa and BASE (Basel Agency for Sustainable Energy) were among the winners of the prestigious Inclusive Growth and Recovery Challenge by data.org, a platform for partnerships committed to build the field of data science for social impact. In their project, the team is developing a mobile app that aims to give smallholder farmers in rural India advice on how to better store their fresh foods and when to sell them. Eight months into the project, the team…
DFKI presents groundbreaking solution for AI-based system development. Whether in the factory, in the operating room or on Mars – the areas of application for modern robots are extremely diverse. This places enormous demands on the capabilities of the systems and leads to increasingly complex development processes. With the completion of the Q-Rock project funded by the German Federal Ministry of Education and Research (BMBF), the Robotics Innovation Center of the German Research Center for Artificial Intelligence (DFKI) presents a…
Quantum computer experiments at UMD show that combining quantum computer pieces doesn’t have to mean combining their error rates. Pobody’s nerfect—not even the indifferent, calculating bits that are the foundation of computers. But JQI Fellow Christopher Monroe’s group, together with colleagues from Duke University, have made progress toward ensuring we can trust the results of quantum computers even when they are built from pieces that sometimes fail. They have shown in an experiment, for the first time, that an assembly…
Groundbreaking research success: Computer scientists from the Cognitive Systems Lab at the University of Bremen have now succeeded in an international project to realize a so-called speech neuroprosthetic. With it, imagined speech can be made acoustically audible – without latency in real time. The advancement can help people who have fallen silent due to neurological diseases and cannot communicate with the outside world without external help. Great research successes require international collaboration: For several years, the Cognitive Systems Lab (CSL)…
