David Reilly and his University of Sidney team developed a silicon chip that can control spin qubits at milli-kelvin temperatures. That’s just slightly above absolute zero (-273.15 degrees Celsius), the temperature at which – theoretically – matter ceases moving. Experts think that spin qubits (where information is encoded onto the magnetic direction of single electrons) …
Diamond CMOS needs symmetrical doping control like we have for semiconductor silicon and diamond n-MOS is needed. The n-channel diamond MOSFETs are demonstrated. This work will enable the development of energy-efficient and high-reliability CMOS integrated circuits for high-power electronics, integrated spintronics, and extreme sensors under harsh environments. Currently, p-channel diamond MOSFETs have been extensively developed …
An AI optical circuit has been made with a neural density equal to 1/400 of human brain. The circuit is trained to process information through unpowered all-optical inference at the speed of light with a computational power more than ten orders of magnitude larger than electronic processors. In future, its neural density is expected to …
