The brief

Analyst view
  • SQC advanced to Stage B of DARPA's Quantum Benchmarking Initiative in November 2025, one of 11 global companies selected.
  • In March 2026, Australia's National Reconstruction Fund invested A$20M for manufacturing; A$40M more in June.
  • Can design, produce and test quantum chips in one week.

Technical approach

As reported
Precision Atom Qubits

Phosphorus atoms in silicon

Phosphorus atoms at atomic scale become spin qubits. Precise placement enables error-corrected quantum computing at scale.

Manufacturing

PAQMan process

The PAQMan process designs, builds and tests quantum chips in <1 week. Fast turnaround lets SQC iterate rapidly and refine designs.

Products

Watermelon and Quantum Twins

Watermelon is quantum machine learning for enterprise. Quantum Twins simulates quantum computing on classical hardware.
