Q-CTRL Raises $290M Series C for Quantum Software and Quantum Navigation
The largest software-focused raise in quantum so far just went to an Australian company. Q-CTRL, based in Sydney, raised US$290M (A$415M) in a Series C led by Salesforce Ventures, which makes it the newest unicorn in the quantum sector, per the company. The release is dated November 12 in Sydney: https://www.einnews.com/pr_news/955914525/
The cap table is unusually strategic. Bullhound Capital and Affinity Partners headline participation. New names include AMD Ventures, EDGE Group, MPower, Australia's National Reconstruction Fund Corporation and SPARX. Returning investors include DCVC, In-Q-Tel, Lockheed Martin Ventures, Main Sequence and Square Peg. The round was expanded twice. The valuation is not disclosed beyond the unicorn claim.
Q-CTRL sells two things. One is infrastructure software that makes noisy quantum hardware usable, which it pitches as AI for quantum: machine learning that tunes and stabilizes qubits. The other is Ironstone Opal, quantum sensing for navigation that works when GPS is jammed or denied. The money goes to scaling both, and the defense names in the round show which one has paying customers sooner.
For the agent crowd this is adjacent rather than core. The interesting overlap is the AI-for-quantum layer: the same automated calibrate, measure, adjust loop that agents are now running on software, applied to physical hardware.
