The Rigetti Forest Software Development Kit includes pyQuil, the Rigetti Quil Compiler (quilc), and the Quantum Virtual Machine (qvm).
Longtime users of Rigetti Forest will notice a few changes. First, the SDK now contains a downloadable compiler and a QVM. Second, the SDK contains pyQuil 2.0, with significant updates to previous versions. As a result, programs written using previous versions of the Forest toolkit will need to be updated to pyQuil 2.0 to be compatible with the QVM or compiler.
After installing the SDK and updating pyQuil in start, see the migration guide to get caught up on what's new!
Quantum Cloud Services will provide users with a dedicated Quantum Machine Image, which will come prepackaged with the Forest SDK. We’re releasing a Preview to the Forest SDK now, so current users can begin migrating code (and share feedback with us early and often!). Longtime Forest users should start with the Migration Guide which outlines key changes in this SDK Preview release.
If you’re new to Forest, we hope this documentation will provide everything you need to get up and running with the toolkit. Once you’ve oriented yourself here, proceed to the section start to get started. If you're new to quantum computing, you also go to our section on intro. There, you’ll learn the basic concepts needed to write quantum software. You can also work through an introduction to quantum computing in a jupyter notebook; launch the notebook from the source folder in pyquil's docs:
cd pyquil/docs/source
jupyter notebook intro_to_qc.ipynbA few terms to orient you as you get started with Forest:
- pyQuil: An open source Python library to help you write and run quantum programs. The source is hosted on github.
- Quil: The Quantum Instruction Language standard. Instructions written in Quil can be executed on any implementation of a quantum abstract machine, such as the quantum virtual machine (QVM), or on a real quantum processing unit (QPU). More details regarding Quil can be found in the whitepaper, A Practical Quantum Instruction Set Architecture.
- QVM: The Quantum Virtual Machine is an open source implementation of a quantum abstract machine on
classical hardware. The QVM lets you use a regular computer to simulate a small quantum computer and execute Quil programs. Find QVM on GitHub.
- QPU: Quantum processing unit. This refers to the physical hardware chip which we run quantum programs on.
- Quil Compiler: The compiler,
quilc, compiles Quil written for one quantum abstract machine (QAM) to another. Our open source compiler will take arbitrary Quil and compile it for the given QAM, according to its supported instruction set architecture. Find quilc on GitHub. - Forest SDK: Our software development kit, optimized for near-term quantum computers that operate as coprocessors, working in concert with traditional processors to run hybrid quantum-classical algorithms. For references on problems addressable with near-term quantum computers, see Quantum Computing in the NISQ era and beyond.
Our flagship product Quantum Cloud Services offers users an on-premise, dedicated access point to our quantum computers. This access point is a fully-configured VM, which we call a Quantum Machine Image. A QMI is bundled with the same downloadable SDK mentioned above, and a command line interface (CLI), which is used for scheduling compute time on our quantum computers. To sign up for our waitlist, please click the link above. If you'd like to access to our quantum computers for research, please email support@rigetti.com.
