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
Preparing diverse cohorts with Black Opal for Digital Catapult’s hybrid learning Quantum Technology Programme
Helping Digital Catapult drive quantum computing adoption through education, industry partnerships, and hands-on learning with Black Opal.
4.8
out of 5 average participant rating for the program, including Black Opal, which was also credited with raising participants' confidence in their quantum computing abilities from 3.1 to 4.2 out of 5 by the end of the course.
Read the case study
The easy-to-use, intuitive Black Opal tool allowed our QTAP participants to quickly get up to speed with quantum computing, ready to trial their real-life business use cases. There was also some great material for participants who were curious to learn more about advanced topics.

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.
Read the case study
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.
