What Q-CTRL Does

Q-CTRL is the world's leading quantum infrastructure-software company, founded in Sydney by Professor Michael Biercuk. Its error-suppression firmware ("Fire Opal") measurably boosts the performance of existing quantum hardware — IBM offers it natively — while its "Boulder Opal" tools serve hardware R&D teams. It has also built a commercial quantum-sensing division for GPS-denied navigation with defense customers across the US, UK and Australia.

Q-CTRL closed a $113M Series B (including extensions) through 2024 with investors including Salesforce Ventures, Airbus Ventures, DCVC and Sequoia — one of the largest raises for a quantum software pure-play.

Technology: Fire Opal error suppression (integrated with IBM Quantum); Boulder Opal hardware characterization; Ironstone Opal quantum navigation, now RTCA DO-160 safety-of-flight-qualified as a GPS backup.
Roadmap: Expanding embedded error-suppression deals across hardware vendors; scaling quantum-navigation contracts with defense primes.
