About
Q-CTRL is a Sydney-based quantum technology company that provides quantum control infrastructure software — firmware and middleware that sits between quantum hardware and application software to actively suppress errors and improve qubit performance. Quantum computers are extremely sensitive to environmental noise that introduces errors in calculations; Q-CTRL's AI-driven control systems continuously monitor and compensate for these errors, dramatically improving the reliability and accuracy of quantum processors without changing the underlying hardware. The company's Black Opal platform provides quantum computing education and training, while Boulder Opal targets research and hardware teams improving their quantum processors. Q-CTRL also develops quantum sensing technology using similar control techniques for navigation, gravimetry, and defense applications. Founded in 2017 by physicist Michael Biercuk, Q-CTRL raised over $77M from investors including Sierra Ventures, Square Peg Capital, and DCVC. The company has established partnerships with quantum hardware providers including IBM, Honeywell (Quantinuum), and IonQ, whose systems benefit from Q-CTRL's error suppression.
