Quantum computers are powerful computational devices that rely on quantum mechanics, or the science of how particles like electrons and atoms interact with the world around them. These devices could potentially be used to solve certain kinds of computational problems in a much shorter amount of time. Scientists have long hoped that quantum computing could be the next great advance in computing; however, existing limitations have prevented the technology from hitting its true potential. For these computers to work, the…
Focus on cybersecurity: Cybercrime incidents are on the rise: To protect information in electronic components from tampering or illicit use, a crack consortium of research institutes, private enterprises, and universities have formed the »Silhouette« project to develop solutions for encrypting data in the optical domain that is considered safe from tampering and eavesdropping. Researchers at Fraunhofer IZM are part of this campaign and are developing a cost-efficient method for the precise coupling of microelectronic components to make data transmissions safer…
… studied at unprecedented resolution: Researchers from the University of Tsukuba and collaborating partners have observed fine-scale exciton dynamics in atomically thin layered materials. This basic study for future optical communications could help replace charge transfer as the standard communications tool. Future optical communication that’s vastly more reliable and faster than what’s commonly available today will require new technology. Modern communication is based on charge transfer, which can result in large transmission losses during certain data-intensive applications. Excitons are alternatives,…
Using existing experimental and computational resources, a multi-institutional team has developed an effective method for measuring high-dimensional qudits encoded in quantum frequency combs, which are a type of photon source, on a single optical chip. Although the word “qudit” might look like a typo, this lesser-known cousin of the qubit, or quantum bit, can carry more information and is more resistant to noise — both of which are key qualities needed to improve the performance of quantum networks, quantum key distribution systems and, eventually,…
In the future, robots will support people with physical disabilities in their own homes. To assess and expand the suitability of robots for everyday activities, the Institute for Artificial Intelligence at the University of Bremen equipped a new research laboratory with a kitchen and furniture. There is also an exact digital image of this lab, known as a “digital twin.” This enables the international research community to develop and test robotic technologies remotely. Carrying out everyday tasks like a human…
Researchers at the TUMCREATE research platform on the Singapore campus of the Technical University of Munich (TUM) have developed CityMoS – City Mobility Simulator. This concept is now supporting the city state in southern Asia in the electrification of transportation. It is also helping to calculate the impact of transportation on the heat generated in the city. CityMoS is already being deployed in Germany, where it is helping with the e transformation of a DHL Freight logistics terminal. How would…
ESnet6 provides over 46 Terabits per second of bandwidth and intelligent network services to support unique data-intensive needs of scientific research. Today, the Energy Sciences Network (ESnet) formally unveiled ESnet6, the newest generation of the U.S. Department of Energy’s (DOE’s) high-performance network dedicated to science. The hybrid in person and virtual event was held at Lawrence Berkeley National Laboratory (Berkeley Lab) and live-streamed on streaming.lbl.gov. “ESnet6 represents a transformational change in the way networks are built for research, with improved capacity, resiliency,…
At Parts2Clean 2022, Fraunhofer IPK will demonstrate how intelligent image processing can contribute to maintaining capital goods. AI-based component and dirt detection in combination with innovative robotics and CO2 cleaning technologies enables the automation of maintenance process chains. Maintenance is a dirty business to begin with: Component contamination must be monitored, and when a certain “dirt level“ is reached, intervention, i.e. cleaning, is required. Researchers at Fraunhofer IPK have developed a technology that uses AI methods such as machine learning…
Scientists have long looked to the brain as an inspiration for designing computing systems. Some researchers have recently gone even further by making computer hardware with a brainlike structure. These “neuromorphic chips” have already shown great promise, but they have used conventional digital electronics, limiting their complexity and speed. As the chips become larger and more complex, the signals between their individual components become backed up like cars on a gridlocked highway and reduce computation to a crawl. Now, a…
The National research center for Cybersecurity ATHENE has found a way to break one of the basic mechanisms used to secure Internet traffic. The mechanism, called RPKI, is actually designed to prevent cybercriminals or government attackers from diverting traffic on the Internet. Such redirections are surprisingly common on the Internet, e.g., for espionage or through misconfigurations. The ATHENE scientist team of Prof. Dr. Haya Shulman showed that attackers can completely bypass the security mechanism without the affected network operators being…
Ionic circuit computes in an aqueous solution. Microprocessors in smartphones, computers, and data centers process information by manipulating electrons through solid semiconductors but our brains have a different system. They rely on the manipulation of ions in liquid to process information. Inspired by the brain, researchers have long been seeking to develop ‘ionics’ in an aqueous solution. While ions in water move slower than electrons in semiconductors, scientists think the diversity of ionic species with different physical and chemical properties…
Researchers at QuTech—a collaboration between the Delft University of Technology and TNO—have engineered a record number of six, silicon-based, spin qubits in a fully interoperable array. Importantly, the qubits can be operated with a low error-rate that is achieved with a new chip design, an automated calibration procedure, and new methods for qubit initialization and readout. These advances will contribute to a scalable quantum computer based on silicon. The results are published in Nature today. Different materials can be used…
New powerful technology reveals lost seabed structures. The ship which sent an iceberg warning to the RMS Titanic, before the ocean-liner sank, has been identified lying in the Irish Sea. In 1912 the merchant steamship SS Mesaba was crossing the Atlantic and sent a warning radio message to the RMS Titanic. The message was received, but never reached the bridge. Later that night, the supposedly unsinkable Titanic hit an iceberg and sank on her maiden voyage, taking 1,500 lives and…
Researchers in quantum technology at Chalmers University of Technology have succeeded in developing a technique to control quantum states of light in a three-dimensional cavity. In addition to creating previously known states, the researchers are the first ever to demonstrate the long-sought cubic phase state. The breakthrough is an important step towards efficient error correction in quantum computers. “We have shown that our technology is on par with the best in the world,” says Simone Gasparinetti, who is head of…
Physicists from Forschungszentrum Jülich and RWTH Aachen University demonstrate electron transport on a quantum chip. Millions of quantum bits are required for quantum computers to prove useful in practical applications. The scalability is one of the greatest challenges in the development of future devices. One problem is that the qubits have to be very close to each other on the chip in order to couple them together. Researchers at Forschungszentrum Jülich and RWTH Aachen University have now come a significant…
Fiber link over 75 kilometers enables new QKD experiments. The Thuringian Ministry of Science has provided eleven million euros in funding for developing an infrastructure for quantum communication networks in the Free State Thuringia, Germany. This includes a fiber-based test route between Jena and Erfurt. Partners of the Fraunhofer Institute for Applied Optics and Precision Engineering IOF have now successfully exchanged quantum keys on the 75 km route for the first time. It is a milestone for the research of…
