Computing, electronics and communications stories
Kyoto University has sent data at 14.6 Gbit/s from a car on a real road to a receiver 140 metres away using the 300 GHz band. It is a research trial at 20 km/h with a fixed antenna, but it moves terahertz radio out of the laboratory.
Ulm-based NVision and Ulm University have shown a single designed molecule working as a light-connected spin qubit. The physics is peer reviewed; the roadmap to on-chip quantum computers is the company’s own.
An HKUST team has stretched room-temperature spin coherence in a perovskite to about five nanoseconds, roughly 300 times longer than a conventional single well. The devices built on it are proofs of concept, not products.
Seoul Viosys says it is mass producing white light from gallium nitride alone, with no rare earth phosphor and no package, in chips as small as 10 micrometres. The claim is the company’s own, and the brightness per chip is tiny.
Cornell has made aluminium gallium oxide conduct at record bandgaps and built test devices. Sapphire offers a manufacturing foothold, but defects and low mobility keep commercial power electronics distant.
Quantum Motion and academic partners used a commercial CMOS process to shrink a quantum-dot charge sensor. Its sensitivity is striking, but the result is not yet high-fidelity spin-qubit readout.
