Real-world use cases

Network Rail

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.

Q-CTRL

Delivering quantum advantage to airborne systems

Q-CTRL’s Ironstone Opal delivers GPS-free quantum navigation, achieving 50x better performance than INS in real-world flight and ground vehicle trials.

50X

improvement over the performance of a strategic-grade inertial navigation system in real flight tests

Read the case study

We achieved an accuracy in some trials comparable to a sharpshooter hitting a bullseye from 1,000 yards away. But because our quantum-assured navigation system allows a vehicle to position itself accurately irrespective of how far it’s travelled, by analogy that sharpshooter can hit the same bullseye no matter how far away they move from the target.

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.
