Start-up hails world’s first quantum computer made from everyday silicon — fits in three 19-inch server racks and is touted as ‘quantum computing’s silicon moment’

A UK start-up says that it has built the world’s first full-stack quantum computer using the same silicon chip technology used in laptops and phones, and it has already been installed at the UK’s National Quantum Computing Centre (NQCC).

Quantum Motion, a 2017 spinout from University College London and Oxford, unveiled the three-rack system on September 15 as part of a government-backed push to commercialize scalable quantum hardware. Built entirely on a conventional CMOS process, the machine is…
