'Rainbow-on-a-chip' could help unlock 6G networks and precision timing for quantum technologies
Loughborough University physicists and an international team have demonstrated that a grain-of-rice-sized microchip can be used to produce a spectrum of precisely spaced frequencies of light, which is then converted into multiple high-frequency electromagnetic signals known as millimeter waves.
Magnetically levitated quantum bit could address design flaws
Researchers at the FAMU-FSU College of Engineering and the National High Magnetic Field Laboratory, headquartered at Florida State University, have designed a new quantum computing architecture that uses magnetic levitation to smooth over design flaws in the intricate components necessary to run a quantum computer.
When different materials transition from one phase to another, such as water coming to a boil or a magnet losing its ability to attract metals, something remarkable can happen: They begin to behave identically, following the same mathematical rules.…
