State University of New York (SUNY) Chancellor John B. King Jr. today announced that this technology is a recipient of the latest round of seed funding through the SUNY Technology Accelerator Fund (TAF), which provides grants to faculty inventors and scientists. This technology is an on-chip quantum sensor platform that leverages arrays of individually addressable single-erbium ion qubits embedded within silicon-based hollow nanopillars. Utilizing advanced nanofabrication and materials engineering, the platform is fully compatible with standard semiconductor foundry processes, enabling scalable and cost-effective production. These quantum devices exhibit exceptional performance at room temperature, unattainable with current technologies.
HardFlow is a new algorithm developed at MIT that helps pretrained generative AI models satisfy hard constraints while improving solution quality without retraining, in applications spanning robotics, control of physical systems, and computer vision.
Researchers observed an anomalous splitting of image-potential states on higher-order topological Bi(111). By tuning film thickness and substrate screening, they linked the splitting to a radial active electric field and the development of Bi(111) surface states. The anomaly provides a possible spectroscopic signature of a monopole-like topological magnetoelectric response.
In this study, the researchers found that the excess number of breast cancer cases detected in the randomised trials closely matched what would be expected in a Danish screening population, where overdiagnosis is estimated to be below 5%.
Superfluid helium could offer a new way to tackle one of the biggest challenges in scaling up quantum computers, say researchers from the University of Surrey. The research team has introduced a conceptual design for a new type of qubit that could be much less vulnerable to errors.
