Integrated quantum computing company Quantinuum Ltd. unveiled new open-source software tools designed to accelerate software development for quantum computing with a more intuitive programming language. The company also announced a new open-source emulator for its Helios quantum computing hardware, Selene, built to model entangled quantum behavior realistically. The new language is called Guppy. The company based the programming language on Python, a widely recognized syntax by developers, which provides an accessible entry point for programming quantum computers. Guppy enables programmers to use code logic, allowing them to create dynamic software with “if/then” statements and “for” loop structures. This higher-level language permits the development of applications that can adjust the path when states change and the code itself is more readable. The new language gives developers access to advanced quantum protocols, including magic state distillation and injection, quantum teleportation and other measurement-based routines. All of them can be executed through a real-time control system. Additionally, users can use Nvidia Corp.’s new CUDA-QX capabilities for error correction, all without needing to write extra code. Quantinuum refers to Selene as a “digital sister” for its Helios quantum computer hardware, providing developers access to an open-source emulator. Selene provides advanced runtime behavior unique to Helios, including measurement-dependent control flow and hybrid quantum-classical logic capabilities. It can also run Guppy programs out of the box, allowing developers to get going immediately. All of this is brought together with the company’s all-in-one quantum computing platform, Nexus, which serves as the middle layer that connects all parts of the stack.
