Silicon spin-based quantum computing has seen substantial progress in the last few years - developments include demonstrations of fidelities above the fault-tolerant threshold and scaling to several-qubit devices, including Quantum Motion's deployment of the first full-stack silicon MOS quantum computer at the UK's National Quantum Computing Centre (NQCC). The development of advanced cryo-electronics and the unique integration opportunities offered by cryo-CMOS hold the keys to unlocking scalable architectures to support utility-scale fault-tolerant quantum computing. We present Quantum Motion's recent work in industrially fabricated cryo-CMOS electronics and qubits, scalable approaches to readout, and thermal characterisation and modelling.
