Overview

• The cryo-CMOS chip operates at milli-kelvin temperatures to control spin qubits without measurable loss of coherence or fidelity.
• The controller’s compact architecture consumes just 10 microwatts overall and 20 nanowatts per megahertz in its analog circuits to support large-scale qubit arrays.
• Demonstrations of one- and two-qubit gates showed negligible degradation compared with conventional room-temperature control setups.
• Published in Nature the study outlines a proof-of-principle path toward integrating millions of qubits on a single quantum processor.
• Emergence Quantum, co-founded by Professor David Reilly and Dr. Thomas Ohki in partnership with UNSW spin-out Diraq, will commercialize the platform.
