Silicon Quantum Computing (SQC)

New Capabilities

Achieved record 99.99% gate fidelity with silicon qubits in December 2025

Quantum computers could help with drug discovery, codebreaking and materials science, but only if they grow from dozens of quantum bits (qubits) to millions. The bottleneck is control: each qubit needs precisely steered light or microwaves, and thousands of cables run into refrigerators colder than deep space. Chipmakers are trying to move that control hardware onto standard production lines, as CU Boulder's December 2025 optical modulator did.
