Q-CTRL

Q-CTRL builds software for controlling quantum systems, improving quantum computing performance, and supporting quantum sensing and navigation.

Q-CTRL says it was founded on November 22, 2017, by Michael J. Biercuk, then a professor at the University of Sydney researching quantum control. The company grew out of his university research on reducing errors and instability in quantum systems. It develops AI-powered infrastructure software for quantum computing and sensing. Its products include tools for quantum hardware control and calibration, error reduction, quantum education, and GPS-free navigation. Q-CTRL joined the IBM Quantum Startup network in 2018. On October 8, 2024, it announced an expanded Series B financing; on April 14, 2025, it announced successful field trials of its quantum navigation technology. The company focuses its business on quantum computing and quantum sensing, describing its work as infrastructure software for making quantum technology useful.
