Overview

Q-CTRL develops software for improving the operation of quantum hardware, along with quantum education and sensing products. Its computing products include Fire Opal and its learning platform includes Black Opal. The company announced $59 million of new equity on October 8, 2024, bringing the aggregate Series B to $113 million. GP Bullhound led the Series B-2 extension.

The incremental investment is $59 million, not a separate $113 million raise. Its business spans computing and sensing, so neither total company financing nor all commercial activity should automatically be attributed to quantum computing alone. Integrations with hardware providers are product relationships, not proof that every partner is a shareholder.

Why Q-CTRL is interesting

Q-CTRL is an infrastructure-software comparison rather than a full-stack processor manufacturer, and its financing includes an extension that must not be counted twice.

Competitive landscape

  • QuantrolOx adjacent

    Automated tuning and calibration; overlapping infrastructure problem but not an identical product.

  • Quantum Machines adjacent

    Control hardware and software; do not treat every control-stack layer as interchangeable.

  • Classiq adjacent

    Quantum-program design and compilation rather than the same hardware-performance layer.
