Our mission is to unlock broad quantum advantage by building software infrastructure that empowers developers to use quantum computing to solve the world’s toughest computational problems.
The past
For more than 50 years, Moore’s Law set the pace of progress in conventional computing. By doubling the number of transistors on a chip roughly every two years, engineers delivered steady gains in speed, efficiency, and cost—driving decades of exponential growth. But that trajectory is now approaching its physical limits.
To keep pushing the boundaries of computing technology, society needs a new type of computer.
The present
Quantum computers represent that next step. Unlike conventional computers, which process information as 0s or 1s, quantum computers use qubits—which can exist in a superposition of both 0 and 1.
By exploiting this uniquely quantum effect, these systems can explore many computational pathways at once and use interference to solve certain problems far more efficiently than classical computers.
They also open the door to tackling challenges that were previously out of reach altogether—from simulating complex physical systems and accelerating machine learning to optimising global supply chains and financial models.
The future
Quantum hardware is advancing at a remarkable pace. Similar to Moore’s Law, the number of qubits in a quantum computer is doubling regularly.
With each additional qubit, simulating quantum systems on classical computers becomes twice as hard. As qubits scale and become more reliable, classical simulation moves out of reach—marking the transition to a new computational era.
Recent breakthroughs at the hardware level suggest that quantum advantage—the point at which quantum computing’s capabilities begin to surpass those of conventional computing—is drawing near.
But hardware alone isn’t enough. No computer is effective without software—and classical code doesn’t run on quantum machines.
Our journey
The most pressing question facing the industry is no longer whether useful quantum computers will exist—but who will program them when they do.
The industry currently faces three major barriers to quantum software development.
- Quantum algorithms must harness interference between the many branches of a quantum superposition to achieve a quantum speed up. Only a few hundred specialists worldwide have demonstrated the ability to formulate such algorithms.
- Most existing quantum programming languages lack higher-level abstraction. Developers must wrestle with the mechanics of circuit construction—rather than focusing on the computational problem itself—hindering the development of solutions to complex problems.
- The hardware landscape is highly fragmented and imperfect. Software written for one device rarely runs efficiently—or at all—on another.
We’re developing software infrastructure that overcomes these barriers and empowers developers to harness quantum computing for practical applications.
Our vision
We believe that programming quantum computers should be as straightforward as programming conventional ones.
Our vision is to make quantum computing accessible to every software developer—regardless of their quantum expertise—and, in doing so, accelerate the widespread commercial adoption of quantum computing.
We’re building software infrastructure and programming tools needed to unite classical and quantum development, and we’re pursuing an ambitious plan to develop tools that can automatically accelerate code written for conventional computers to run on quantum machines.
