KIT researchers work on new qubit approach – publication in Nature Materials. Quantum computers can more rapidly process large amounts of data, because they carry out many computation steps in parallel. The information carrier of the quantum computer is a qubit. Qubits do not only possess the information of “0” and “1,” but also values in between. However, the difficulty consists in producing qubits that are small enough and can be switched quickly enough to execute quantum calculations. A very…
New study aims to advance quantum computing. An international team of researchers, including scientists from Jena, has succeeded in developing a new and particularly precise type of measurement in tiny quantum systems. Applications are conceivable in semiconductor manufacturing, for example, but also in mobile radio technology or microscopy in the future. Experimental tests to prove the study were carried out on Germany’s first quantum computer, the Fraunhofer “QSystemOne”, among others. The researchers have now published their results in the journal…
Discovery of previously unknown effect makes compact, ultra-fast control of spin qubits possible. Australian engineers have discovered a new way of precisely controlling single electrons nestled in quantum dots that run logic gates. What’s more, the new mechanism is less bulky and requires fewer parts, which could prove essential to making large-scale silicon quantum computers a reality. The serendipitous discovery, made by engineers at the quantum computing start-up Diraq and UNSW Sydney, is detailed in the journal Nature Nanotechnology. “This…
Global warming is partly due to the vast amount of carbon dioxide that we release, mostly from power generation and industrial processes, such as making steel and cement. For a while now, chemical engineers have been exploring carbon capture, a process that can separate carbon dioxide and store it in ways that keep it out of the atmosphere. This is done in dedicated carbon-capture plants, whose chemical process involves amines, compounds that are already used to capture carbon dioxide from…
Researchers at the University of Massachusetts Amherst use the body to harvest waste energy to power wearable devices. While you may be just starting to reap the advantages of 5G wireless technology, researchers throughout the world are already working hard on the future: 6G. One of the most promising breakthroughs in 6G telecommunications is the possibility of Visible Light Communication (VLC), which is like a wireless version of fiberoptics, using flashes of light to transmit information. Now, a team of…
The EU project TEF-Health aims to test and validate innovative artificial intelligence (AI) and robotics solutions for the healthcare sector and accelerate their path to market. It is led by Prof. Petra Ritter, who heads the Brain Simulation Section at the Berlin Institute of Health at Charité (BIH) and at the Department of Neurology and Experimental Neurology of Charité – Universitätsmedizin Berlin. The 51 participating project partners from nine European countries will receive funding to the tune of about €60…
Using Fraunhofer technology to plan the factories of tomorrow. The factories of the future have significant demands to meet – including the ability to adapt to production processes quickly and function within tight spaces that come at a high operating cost. Mixed reality can provide efficient support for factory planning in exactly this kind of scenario. Through their HoloLayouts software, researchers at the Fraunhofer Institute for Manufacturing Engineering and Automation IPA have developed an application in which multiple people can…
Emerging forms of thin-film device technologies that rely on alternative semiconductor materials, such as printable organics, nanocarbon allotropes and metal oxides, could contribute to a more economically and environmentally sustainable internet of things (IoT), a KAUST-led international team suggests. The IoT is set to have a major impact on daily life and many industries. It connects and facilitates data exchange between a multitude of smart objects of various shape and size — such as remote-controlled home security systems, self-driving cars…
Controlling the rotation of this molecule could lead to new technologies for microelectronics, quantum computing and more. You can easily rotate a baseball in your hand by twisting your fingers. But you need inventive scientists with access to world-class scientific facilities to rotate an object that is only two billionths of a meter wide. That is a million times smaller than a raindrop. Scientists at the U.S. Department of Energy’s (DOE) Argonne National Laboratory report they can precisely rotate a…
Exploring a new way to teach robots, Princeton researchers have found that human-language descriptions of tools can accelerate the learning of a simulated robotic arm lifting and using a variety of tools. The results build on evidence that providing richer information during artificial intelligence (AI) training can make autonomous robots more adaptive to new situations, improving their safety and effectiveness. Adding descriptions of a tool’s form and function to the training process for the robot improved the robot’s ability to…
Processing devices based on polarized light run one million times faster than current technology. Logic gates are the fundamental components of computer processors. Conventional logic gates are electronic – they work by shuffling around electrons – but scientists have been developing light-based optical logic gates to meet the data processing and transfer demands of next-generation computing. New optical chirality logic gates developed by researchers at Aalto University operate about a million times faster than existing technologies, offering ultrafast processing speeds….
… that drive development. Scientists at Johns Hopkins Medicine say they have developed a computer model — dubbed quantitative fate mapping — that looks back in the developmental timeline to trace the origin of cells in a fully grown organism. The new model, they say, can help researchers more precisely spot which cells acquire alterations during development that change an organism’s fate from healthy to disease states, including cancer and dementia. The achievement, described in the Nov. 23 issue of…
Mathematical analysis identifies a vortex structure that is impervious to decay. Scientists have shown how three vortices can be linked in a way that prevents them from being dismantled. The structure of the links resembles a pattern used by Vikings and other ancient cultures, although this study focused on vortices in a special form of matter known as a Bose-Einstein condensate. The findings have implications for quantum computing, particle physics and other fields. Postdoctoral researcher Toni Annala uses strings and…
No wall is too steep for them, they walk upside down on ceilings, their fine-haired feet stick better than any professional glue without leaving any traces, and they defy gravity: the feet of geckos! They are of equal interest to researchers in materials science and in AI research. This effect of the gecko’s feet is now to be exploited in the joint project “GecKI“ to develop energy-efficient, auto-adaptive and product-independent adhesive pads for robotic gripping systems. The German Federal Ministry…
… could enable higher-res displays. FINDINGS A UCLA team has developed a technology for projecting high-resolution computer-generated images using one-sixteenth the number of pixels contained in their source images. The system compresses images based on an artificial intelligence algorithm, and then decodes them using an optical decoder — a thin, translucent sheet of plastic produced using a 3D printer — that is designed to interact with light in a specific way as part of the same algorithm. The decoder consumes…
… promotes 6G and secure wireless communications. A research team co-led by a scientist at City University of Hong Kong (CityU) has developed a novel antenna that allows manipulation of the direction, frequency and amplitude of the radiated beam, and is expected to play an important role in the integration of sensing and communications (ISAC) for 6th-generation (6G) wireless communications. The structure and characteristics of traditional antennas cannot be changed once fabricated. However, the direction, frequency, and amplitude of the…
