Enabling a Quantum Revolution
Quantum computing has the potential to transform how we tackle hard computational problems. At Horizon Quantum, we're building tools to empower developers to redefine what's possible.
Who We Are
Horizon Quantum is developing a new generation of programming tools to simplify and expedite the process of developing software for quantum computers.
By removing the need for prior quantum computing experience to develop applications for quantum hardware, Horizon’s tools will make the power of quantum computing accessible to every software developer.
Why Horizon Quantum
At Horizon Quantum, we are bridging the gap between quantum hardware and software developers.
We make programming tools that allow developers to work at higher levels of abstraction rather than focusing on quantum physics or hardware requirements.
To achieve this, we are automating the construction of quantum algorithms from classical code and making programming a quantum computer more like conventional software engineering. Our goal is to enable all developers, regardless of their quantum expertise, to harness the power of quantum computers.
