cirq-core 1.6.1

A framework for creating, editing, and invoking Noisy Intermediate Scale Quantum (NISQ) circuits.

cirq-core

Cirq is a Python package for writing, manipulating, and running quantum circuits on quantum computers and simulators. Cirq provides useful abstractions for dealing with today’s noisy intermediate-scale quantum (NISQ) computers, where the details of quantum hardware are vital to achieving state-of-the-art results. For more information about Cirq, please visit the Cirq documentation site.

This Python module is cirq-core, which contains all the code you need to write quantum algorithms for NISQ devices and run them on the built-in Cirq simulators.

To run algorithms on a given quantum computing platform, you will also need to install an appropriate Cirq hardware interface module. Please visit the hardware section of the Cirq documentation site for information about the hardware interface modules currently available.

Installation

There are two installation options for the cirq-core module:

• To install the stable version of cirq-core, use

  pip install cirq-core
  

• To install the latest pre-release version of cirq-core, use

  pip install --upgrade cirq-core~=1.0.dev
  

  (The ~= has a special meaning to pip of selecting the latest version compatible with the 1.* and dev in the name. Despite appearances, this will not install an old version 1.0 release!)

If you would like to install Cirq with all the optional modules, not just cirq-core, then instead of the above commands, use pip install cirq for the stable release or pip install --upgrade cirq~=1.0.dev for the latest pre-release version.
