Building quantum computers from the qubit up

At Nord Quantique, we’re building fault-tolerant quantum computers from the qubit up with the goal of making quantum computing practical at scale. We’re a Canadian company based in Sherbrooke, Québec, where we develop superconducting quantum computers that integrate quantum error correction directly into the hardware. Rather than accept that useful quantum computers will require millions of physical qubits, we’ve taken a different path by designing qubits that are intrinsically more resilient to errors through bosonic encoding. It fundamentally changes the economics and engineering of quantum computing by reducing the hardware overhead needed to build useful systems.

We embed error correction directly into the hardware via superconducting bosonic codes to achieve a 1:1 logical-to-physical qubit ratio. The company recently advanced to Stage B of DARPA’s Quantum Benchmarking Initiative and reached unicorn status with a $1.4B valuation in our latest funding round.

Reliable computations

The biggest challenge in quantum computing isn’t creating qubits—it's performing reliable computations with them. Quantum information is extraordinarily fragile: Every operation, measurement, or interaction with the environment introduces errors that quickly accumulate. Quantum error correction is essential, because it allows errors to be detected and corrected while computations are running.
