cirq-google 1.5.0.dev20250307230418

The Cirq module that provides tools and access to the Google Quantum Computing Service

⚠️ WARNING
This is a development version of cirq-google and may be unstable. For the latest stable release of cirq-google, please visit https://pypi.org/project/cirq-google.

cirq-google

This is the Cirq-Google integration module. It provides an interface to Google's Quantum Computing Service, and also contains additional tools for calibration and characterization of Google's quantum hardware devices.

Please note!
Google's quantum hardware is currently available only to authorized partners. Access requires an application, usually with a Google sponsor.

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.

Installation

This module is built on top of Cirq; installing this module will automatically install cirq-core and other dependencies. There are two installation options for the cirq-google module:

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

  pip install cirq-google
  

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

  pip install cirq-google~=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-google, then instead of the above commands, use pip install cirq for the stable release or pip install cirq~=1.0.dev for the latest pre-release version.
