This achievement may enable efficient control of large semiconductor qubit arrays. The research group published their demonstration of hopping spins in Nature Communications and their work on somersaulting spins in Science. In 1998, Loss and DiVincenzo published the seminal work ‘quantum computation with quantum dots’. In their original work, hopping of spins was proposed as a basis for…
UVA researchers sharpen machine vision by mimicking nature and taking advanced computing to the edge. Self-driving cars occasionally crash because their visual systems can’t always process static or slow-moving objects in 3D space. In that regard, they’re like the monocular vision of many insects, whose compound eyes provide great motion-tracking and a wide field of view but poor depth perception. Except for the praying mantis. A praying mantis’ field of view also overlaps between its left and right eyes, creating…
A new platform lets PME researchers combine atom array processors with photonic and semiconductor chips. Quantum information systems offer faster, more powerful computing methods than standard computers to help solve many of the world’s toughest problems. Yet fulfilling this ultimate promise will require bigger and more interconnected quantum computers than scientists have yet built. Scaling quantum systems up to larger sizes, and connecting multiple systems, has proved challenging. Now, researchers at the University of Chicago’s Pritzker School of Molecular Engineering…
An international collaboration seeks to innovate the future of how a mechanical man’s best friend interacts with its owner, using a combination of AI and edge computing called edge intelligence. The project is sponsored through a one-year seed grant from the Institute for Future Technologies (IFT), a partnership between New Jersey Institute of Technology (NJIT) and Ben-Gurion University of the Negev (BGU). Assistant Professor Kasthuri Jayarajah in NJIT’s Ying Wu College of Computing is researching how to design a socially assistive model…

Then, precise fabrication methods are used to make the…
The low-cost cellphone-based Raman spectrometer system can make identifications of unknown biological molecules within minutes. Imagine knowing what berry or mushroom is safe to eat during a hike or swiftly detecting pathogens in a hospital setting that would traditionally require days to identify. Identification and detection of drugs, chemicals and biological molecules invisible to the human eye can be made possible through the combined technology of a cellphone camera and a Raman spectrometer — a powerful laser chemical analysis method….
A new concept offering the potential for more efficient data storage. Researchers from the Helmholtz-Zentrum Dresden-Rossendorf (HZDR), TU Chemnitz, TU Dresden and Forschungszentrum Jülich have been the first to demonstrate that not just individual bits, but entire bit sequences can be stored in cylindrical domains: tiny, cylindrical areas measuring just around 100 nanometers. As the team reports in the journal Advanced Electronic Materials (DOI: 10.1002/aelm.202400251), these findings could pave the way for novel types of data storage and sensors, including…

Scientists have made a significant breakthrough in creating a new method for transmitting quantum information using particles of light called qudits. These qudits promise a future quantum internet that is both secure and powerful. Traditionally, quantum information is encoded on qubits, which can exist in a state of 0, 1, or both at the same time (superposition). This quality makes them ideal for complex calculations but limits the amount of data they can carry in communication. Conversely, qudits can encode…
EPFL engineers have created a device that can efficiently convert heat into electrical voltage at temperatures lower than that of outer space. The innovation could help overcome a significant obstacle to the advancement of quantum computing technologies. To perform quantum computations, quantum bits (qubits) must be cooled down to temperatures in the millikelvin range (close to -273 Celsius), to slow down atomic motion and minimize noise. However, the electronics used to manage these quantum circuits generate heat, which is difficult…
A team from the University of Würzburg is developing an AI-based attitude control system that will allow satellites to maneuver autonomously. The new technology will be tested in space.

It is being developed by two computer science departments at the University of Würzburg (JMU) using a…
Is it possible to decode how we feel from our movements? How can emotions be studied “from the outside” by using empirical methods?
