Diraq aims for a utility-scale silicon quantum computer by 2031

Due 2031

Diraq says it will reach utility scale by 2031, with more than 2 million physical qubits on a single silicon chip and more than 10,000 logical qubits (error-protected qubits), two years ahead of the schedule of DARPA's Quantum Benchmarking Initiative.

Predicted by: Diraq
Type: Official company roadmap
Said on: Aug 27, 2026
Original deadline: by 2031 (2031)
Status: Pending
Counts toward: the Quantum Supremacy estimate
