CMOS Silicon Spin Qubit Chips

Quantum processor chips fabricated using standard CMOS semiconductor manufacturing processes, enabling production at existing silicon fabs without specialized quantum fabrication lines. Demonstrated single-qubit gate fidelities of 99.9% on industrially produced silicon quantum dots in 2025 in collaboration with imec. Designed to scale to billions of qubits per chip using existing semiconductor infrastructure, with physical qubit costs projected below $1. Backed by $38M from the U.S. CHIPS Act.
