Diraq reports high-fidelity silicon qubits made on a 300-mm foundry line
Oct 21, 2024
A Diraq-led team reports a two-qubit silicon device fabricated on a 300-mm semiconductor line. Gate-set tomography finds single- and two-qubit control above 99% fidelity and state preparation and measurement above 99.9%; this is a small device, not a wafer-sized processor.
Why it matters
Retaining accurate quantum control after industrial fabrication is a prerequisite for scaling silicon-spin processors beyond laboratory devices.
