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. The problems are the same across both applications of quantum. Our AI solutions are transformational.

Deploying quantum in the real world

Through our unique focus on AI‑for‑quantum we’ve achieved what no one else can, delivering the first true quantum advantage in both GPS-free navigation and in quantum computing for materials simulation.

We’ve learned that the same technology that can make a quantum sensor work on a moving airplane fixes the errors in a quantum computer.

We build the AI solutions that take quantum from the lab to the real world, from data centers to autonomous vehicles.

Real-world use cases

This collaboration demonstrates how hybrid quantum workflows can become practical tools for computer-aided drug discovery, enabling us to explore computational approaches that were previously out of reach.
Jean-Philip Piquemal
Co-founder
Solving the distribution network reconfiguration problem requires advanced optimization approaches that can combine the strengths of classical and quantum computing. Working with Q-CTRL enabled us to construct a hybrid quantum-classical workflow that leverages these combined strengths, unlocking the performance available on IBM Quantum hardware through Fire Opal’s optimization and error suppression capabilities.
Hiromichi Matsuyama
R&D Department Manager

Q-CTRL played a key role in extending our quantum collision-model simulations of Markovian quantum processes on IBM superconducting hardware. Their hardware-aware execution expertise, together with Fire Opal's error-management software, helped us achieve long-time simulations beyond previously demonstrated scales.
Seiji Yunoki
Chief Scientist & Team Leader

We achieved a significant leap forward in accurately calculating the physical properties of materials, demonstrating a five-fold increase in achievable circuit width over previous Quantum Phase Estimation studies.
Shu Kanno
Scientist

Working with Q-CTRL gave us a chance to explore a new and fast moving area of technology in a way that was grounded in our real design challenges. The team brought a strong mix of technical expertise and practical focus, helping us understand how quantum machine learning might fit into our workflow. It was a productive and insightful collaboration.

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.

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.

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.

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.

The breadth and flexibility of Boulder Opal allowed us to create our own optimization scenario and obtain pulses robust to the five most relevant experimental noise sources at the same time! This will be crucial in the development of atomic interferometers to detect dark matter and gravitational waves at currently unexplored frequencies.
