The platform is made up of components that are each versioned and released on their own schedule. Each platform release is a tested set of compatible component versions, with notes on what is new and what you need to know before upgrading.

How the platform fits together

Latest

The first named release of the platform. It adds a framework for fault-tolerant programming with quantum error correction codes, and libraries of reusable algorithmic primitives.

Highlights

Guppy FT

Fault-tolerant development framework

Guppy FT defines quantum error correction code architectures and compiles ordinary Guppy programs into fault-tolerant implementations, so you can experiment with different fault-tolerance approaches without rewriting your algorithm.

Guppy Algorithms

Reusable quantum algorithm libraries

Guppy Algorithms is a growing collection of building blocks for quantum simulation, linear algebra, arithmetic and other common patterns, so you can assemble applications from proven components.

Important information

  • The first platform release. Before v26.1, each component was released independently. Platform releases now publish a tested set of compatible component versions, listed below. Components continue to publish their own releases in between.
  • Pin your environment to the release with the install command below, so that Guppy, Guppy FT and Guppy Algorithms resolve to versions that work together.

Breaking changes

None in this release.
