pytket-qsharp 0.19.0

Extension for pytket, providing access to Azure devices and simulators via Microsoft QDK

pytket-qsharp

Pytket is a Python module for interfacing with CQC tket, a set of quantum programming tools.

Azure Quantum is a portal for accessing quantum computers via Microsoft Azure.

Microsoft's QDK is a language and associated toolkit for quantum programming.

pytket-qsharp is an extension to pytket that allows pytket circuits to be executed on remote devices and simulators via Azure Quantum, as well as local simulators and resource estimators from the Microsoft QDK.

Getting started

pytket-qsharp is available for Python 3.7, 3.8 and 3.9, on Linux, MacOS and Windows. To install, run:

pip install pytket-qsharp

In order to use pytket-qsharp you will first need to install the dotnet SDK (3.1) and the iqsharp tool. On some Linux systems it is also necessary to modify your PATH:

1. See this page for instructions on installing the SDK on your operating system.

2. On Linux, ensure that the dotnet tools directory is on your path. Typically this will be ~/.dotnet/tools.

3. Run dotnet tool install -g Microsoft.Quantum.IQSharp.

4. Run dotnet iqsharp install --user.

Alternatively, you can set up an environment with all the required packages using conda:

conda create -n qsharp-env -c quantum-engineering qsharp notebook

conda activate qsharp-env

Backends provided in this module

This module provides four backends, all deriving from the pytket Backend class:

• AzureBackend, for executing pytket circuits on targets the user has access to on Azure Quantum;

• QsharpSimulatorBackend, for simulating a general pure-quantum circuit using the QDK;

• QsharpToffoliSimulatorBackend, for simulating a Toffoli circuit using the QDK;

• QsharpEstimatorBackend, for estimating various quantum resources of a circuit using the QDK. This provides a get_resources method, which returns a dictionary.
