Building the software infrastructure to power tomorrow’s computers

Recent hardware advances suggest that the quantum advantage is drawing near—with the potential to transform industries.

But hardware is only half the picture. No computer is effective without software, and classical code doesn’t run on quantum machines.

Only a few hundred specialists worldwide have the skills needed to formulate quantum algorithms. The question facing the industry is no longer whether useful quantum computers will exist—but who will program them when they do.

What if programming a quantum computer was as simple as writing a Python script?

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 only choice for serious quantum software development

With proprietary languages and a powerful compiler, Triple Alpha, Horizon’s integrated development environment (IDE), enables developers to create advanced, portable quantum programs.

By leveraging Horizon Quantum's deployment and execution infrastructure, users can run these applications on today’s hardware.

Deploy applications as APIs

Developers can choose the entry point that best fits their needs—whether writing high-level applications, working closer to the assembly-like layer, or programming directly at the hardware level.

Designed to overcome the applications bottleneck

Three interrelated challenges are creating an applications bottleneck—one that threatens to constrain the development of scalable software and slow the commercial adoption of quantum computing.

The ability to harness quantum effects gives quantum computers their power. However, leveraging quantum mechanics is also what makes constructing quantum algorithms so difficult. Formulating algorithms designed to solve real-world problems demands a deep knowledge of quantum physics alongside domain expertise in areas like chemistry or finance. Only a few hundred specialists worldwide have this skillset, meaning that most developers must shoehorn their problems into a narrow range of existing algorithms rather than create new ones tailored to their use case.

Most quantum programming languages lack higher-level abstraction. They take a gate-level approach that forces developers to wrestle with the mechanics of circuit construction rather than focus on the computational problem itself. This granular approach makes sophisticated quantum software development impractical because it requires effort similar to developing a processor for each individual problem.

The quantum hardware landscape is diverse and highly fragmented. Competing modalities each have their own strengths and limitations. Connectivity constraints, instruction sets, and noise vary widely, meaning software written for one device is unlikely to run efficiently—or at all—on another.
