Libraries and fault tolerance
Developer tools
Third-party tools we interface with.
Catalogue
Every component, by layer
Guppy toolkit
Guppy
Quantum-first programming language embedded in Python, with measurement-dependent control flow, strong types, qubit safety and compile-time metaprogramming.
Get startedSelene
Emulation framework for hybrid quantum-classical programs. Selene ships with guppylang and powers its emulator module.
User guideTKET
Quantum SDK and optimizing compiler for building circuits, reducing their resource cost and targeting many devices and simulators.
User guideGuppy FT
Fault-tolerance framework for Guppy. Write a program once, then encode it with quantum error correction codes such as the Steane code; the encoded program runs on Selene, through Nexus and on Helios.
Guided workflowGuppy Algorithms
Library of reusable algorithmic primitives for Guppy programs.
Guppy Algorithms getting started
Nexus Console
Systems support
Submit, cost and monitor jobs on Quantinuum systems, and keep programs and results together in Nexus projects.
Submit a job to HeliosEmulators
Cloud-hosted emulators of Quantinuum systems for debugging and optimizing programs before using hardware.
Quantinuum emulators for HeliosGuppy Playpond
Write and run Guppy programs in the browser, with nothing to install.

Quantinuum systems
Helios
Quantinuum's next-generation system, programmed with Guppy and accessed through the Nexus Console.
Submit a job to HeliosSystem Model H2
Trapped-ion QCCD quantum computer, programmed with pytket, or with Guppy compiled to QIR.
Job submission with pytket and Nexus
