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.

Real-world use cases

The University of Sydney

Unlocking hardware-efficient quantum gates with the ‘Rosetta stone’ of code

Boulder Opal enabled precision control of trapped-ion vibrations, realizing error-correctable qubits in a compact, hardware-efficient form.

2 in 1

Achieved 2 error-correctable logical qubits in 1 atom, reducing hardware demand and enabling scalable, hardware-efficient quantum processing.

Read the case study

Effectively, we store two error-correctable logical qubits in a single trapped ion and demonstrate entanglement between them. We did this using quantum control software developed by Q-CTRL, with a physics-based model to design quantum gates that minimise the distortion of GKP logical qubits, so they maintain the delicate structure of the GKP code while processing quantum information.

Digital Catapult

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.

Delivering quantum advantage to airborne systems

Q-CTRL’s Ironstone Opal delivers GPS-free quantum navigation, achieving 94X better performance than INS in real-world flight and ground vehicle trials.

94X

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.
