New approach could help quantum networks to support more users without losing data. 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. The method, demonstrated in a paper published in Optica, could help lay the groundwork for when a large number of quantum computers, quantum sensors…
Automated approach transformative for computational materials science. A revolutionary machine-learning (ML) approach to simulate the motions of atoms in materials such as aluminum is described in this week’s Nature Communications journal. This automated approach to “interatomic potential development” could transform the field of computational materials discovery. “This approach promises to be an important building block for the study of materials damage and aging from first principles,” said project lead Justin Smith of Los Alamos National Laboratory. “Simulating the dynamics of…
Over the past years, global data traffic has experienced a boom, with over 12.5 billion connected devices all over the world. The current world-wide deployment of the 5G telecommunications standard is triggering the need for smaller devices with enhanced performances, such as higher speed, lower power consumption and reduced cost as well as easier manufacturability. In search for the appropriate technology, photonic devices emerged as the leading technology for the evolution of such information and communication technologies, already surpassing the…
… between machines, plants and cloud systems thanks to Time Sensitive Networking Being able to reliably and safely control and regulate highly dynamic production systems still appears to be a challenge for many companies. Edge and cloud systems are gaining in importance, but even today there is still a lack of appropriate equipment and infrastructure to integrate existing machines and plants into digital IT landscapes in accordance with the industrial requirements. To this end, the Fraunhofer Institute for Production Technology…
An international research team has developed a unique platform to program a layered crystal, producing imaging capabilities beyond common limits on demand. The discovery by the team from Columbia University, the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) in Hamburg, the University of California-San Diego, the University of Washington, and the Flatiron Institute is an important step toward the control of nanolight – light that can access the smallest length scales imaginable. The work, now published…
AI in urban test: Fraunhofer IAO and the City of Karlsruhe explore the management of parking in residential areas How many cars park on a street at any one time? Are there enough spaces for all the cars that habitually park there? Or might it be an idea to create a residential parking zone? To answer these questions, municipalities have to invest a lot of time and effort in counting vehicles and investigating the situation on the ground. In a…
With the help of AI, Landshut University of Applied Sciences wants to optimise internal company logistics and therefore increase the competitiveness of production industries in Bavaria No other technology is changing our society and world of work quite as rapidly as artificial intelligence (AI). To be economically successful in the market, in addition to a good product, optimised and intelligent production processes are of considerable importance. A research team at the Technology Centre for Production and Logistics Systems (TZ PULS)…
ZIM cooperation network on AI-based agricultural robotics launched The recently approved ZIM cooperation network “DeepFarmbots” met virtually for its official kick-off on November 25. The central goal of the network is to develop and disseminate new agricultural robotics solutions for efficient and sustainable agriculture. In an interdisciplinary approach, agricultural robotics is to be linked with new deep learning methods and the synergy effects between the partners are to be deepened. The Leibniz Centre for Agricultural Landscape Research (ZALF) is participating…
… using AI and supercomputers UT Arlington computer scientists use TACC systems to generate synthetic objects for robot training. Before he joined the University of Texas at Arlington as an Assistant Professor in the Department of Computer Science and Engineering and founded the Robotic Vision Laboratory there, William Beksi interned at iRobot, the world’s largest producer of consumer robots (mainly through its Roomba robotic vacuum). To navigate built environments, robots must be able to sense and make decisions about how…
Computer simulations of cells evolving over tens of thousands of generations reveal why some organisms retain a disused switch mechanism that turns on under severe stress, changing some of their characteristics. Maintaining this “hidden” switch is one means for organisms to maintain a high degree of gene expression stability under normal conditions. Tomato hornworm larvae are green in warmer regions, making camouflage easier, but black in cooler temperatures so that they can absorb more sunlight. This phenomenon, found in some…
Complex production processes in highly flexible and networked manufacturing systems require all processes and distributed systems to be able to exchange their data extremely reliably and with only short delay times. For this so-called “Ultra Reliable and Low Latency Communication” (URLLC), the 3rd Generation Partnership Project (3GPP), a worldwide cooperation for the standardization of mobile communication technologies, is developing a new standard for future 5G products. The Fraunhofer-Institute for Production Technology IPT and the Swedish mobile communications supplier Ericsson are…
Wireless power transfers in the ocean For drones that can be stationed underwater for the adoption of ICT in mariculture. Associate professor Masaya Tamura, Kousuke Murai (who has completed the first term of his master’s program), and their research team from the Department of Electrical and Electronic Information Engineering at Toyohashi University of Technology have successfully transferred power and data wirelessly through seawater by using a power transmitter/receiver with four layers of ultra-thin, flat electrodes. In the field of wireless…
For the first time, physicists from the University of Innsbruck have entangled two quantum bits distributed over several quantum objects and successfully transmitted their quantum properties. This marks an important milestone in the development of fault-tolerant quantum computers. The researchers published their report in Nature. Even computers can miscalculate. Already small disturbances change stored information and corrupt results. That is why computers use methods to continuously correct such errors. In quantum computers, the vulnerability to errors can be reduced by…
Study shows improvements to chemical sensing chip that aims to quickly and accurately identify drugs and other trace chemicals. University at Buffalo researchers are reporting an advancement of a chemical sensing chip that could lead to handheld devices that detect trace chemicals — everything from illicit drugs to pollution — as quickly as a breathalyzer identifies alcohol. The chip, which also may have uses in food safety monitoring, anti-counterfeiting and other fields where trace chemicals are analyzed, is described in…
To perform calculations, quantum computers need qubits to act as elementary building blocks that process and store information. Now, physicists have produced a new type of qubit that can be switched from a stable idle mode to a fast calculation mode. The concept would also allow a large number of qubits to be combined into a powerful quantum computer, as researchers from the University of Basel and TU Eindhoven have reported in the journal Nature Nanotechnology. Compared with conventional bits,…
A new era of mobile communication is about to begin: Transmitting a whole terabit of data, one thousand gigabits, per second. Dr. Ivan Ndip, specialist for antenna and high-frequency systems at the Fraunhofer Institute for Reliability and Microintegration IZM in Berlin speaks about current progress with 6G and its many possible applications. What does 6G stand for? Dr. Ndip: 6G is the sixth generation of mobile communication. With 5G, we had data rates of up to 20 gigabit per second…
