Linking silicon T centres with light offers a route to fault-tolerant quantum computing

Physics World spoke with Simmons earlier this month in London at Commercialising Quantum Global 2024, which was organized by Economist Impact. She explains how the company’s qubits – based on T-centre spins in silicon – are connected using telecoms-band photons. Simmons makes the case that the technology can be integrated and scaled to create fault-tolerant computers. We also chat about the company’s manufacturing programme and career opportunities for physicists at the firm.
