Q-CTRL holds the key to the multi-trillion-dollar quantum opportunity
McKinsey calls quantum a $2T market opportunity. Achieving this value is blocked by the divide between the quantum and classical worlds.
We build AI-powered infrastructure software to bridge this gap, delivering performance no one else can match. With this unique capability we’ve focused our business around the twin verticals of quantum computing and quantum sensing.
First and only in the world to deliver quantum advantage
Through our unique focus on AI-for-quantum we’ve achieved what no one else can, delivering the first true quantum advantage in GPS-free navigation and setting world records in quantum computer performance.
The team making quantum technology useful
Through advanced research that leads the field, and a dedicated focus on customer value through our products, we’re committed to delivering the full potential of quantum technology.

Real-world use cases
Accelerating the schedule for quantum-enhanced rail
Accelerate the usefulness of quantum computing for rail scheduling through custom solution development and performance optimization utilizing Fire Opal.
6X
increase in solvable problem size and accelerated timeline to practical quantum advantage by up to 3 years, now estimated for 2028.

We were pleasantly surprised to see the optimal routing of 26 trains over 18 minutes of real scheduling data for the full station topology being realised on a real quantum device, which otherwise wouldn’t have been possible without using Q-CTRL’s optimisation solver.

Improving quantum education outcomes with Black Opal at the University of Hull, UK
Enhancing student engagement and real-world understanding in quantum computing through intuitive and interactive learning with Black Opal.
85%
of students reported that Black Opal improved their overall learning outcomes when used alongside their university syllabus, and would recommend its use in future courses.
Read the case study
Students who engaged with Black Opal as an active companion resource significantly boosted knowledge retention and ultimately understanding. Some of them even engaged further with quantum computing by choosing a final-year project in that field.

Nord Quantique is accelerating the path to useful quantum error correction with Boulder Opal
Nord Quantique used Boulder Opal to design a hardware-efficient QEC protocol for a superconducting system where quantum information is encoded in GKP states.
14%
increase in logical qubit lifetime
Read the case study
Given the complexity of the physics at play, being able to perform closed-loop optimization of a few physically motivated parameters of the quantum error correction protocol with Boulder Opal is very valuable to us.

Improving Army logistics with quantum computing
With Fire Opal, the Australian Army tested and validated a quantum computing solution on real hardware that promises to outperform their existing methods.
12X
improvement in the likelihood of finding an optimal solution with Fire Opal over the default hardware execution
Read the case study
Optimally routing 120 convoys can take more than a month of classical computation. The Australian Army is evaluating the potential of quantum computing to provide improvements; however, it’s been difficult to validate the feasibility of a quantum solution due to hardware noise. With Fire Opal, an algorithmic enhancement software, we are able to achieve results on quantum computers that build confidence in our quantum roadmap.
