Full-stack quantum hardware and software solutions
Quantinuum provides both quantum hardware and software. Its H1-1 processor runs quantum circuits, while TKET is an open-access, architecture-independent software stack that lets developers design circuits that work across different quantum devices. It differs from competitors by delivering quantum-hardened encryption keys at the device level and offering a complete hardware-software package, plus it has demonstrated strong performance by passing the Quantum Volume 32,768 benchmark. Its goal is to help solve real-world problems like drug discovery, new materials design, and supply-chain optimization while keeping data secure against evolving quantum threats.
