Diraq

Diraq builds quantum computers using spin qubits based on modified silicon transistors, fabricated with standard CMOS semiconductor foundry processes. Its technology roadmap targets millions of qubits on a single chip and quantum processing units sized for a single data-center rack. The company has headquarters in Sydney, Australia, and Palo Alto, California, with additional facilities in Melbourne, Los Angeles and Chicago. It also publishes research on silicon spin qubit fidelity and control.
