Cirq v1.6.0 release

Summary

Removed the Cirq-Rigetti package. Increased the minimum Python version to 3.11.
Enhanced support for experiment types and circuits for Quantum Engine.
Added a new Quantum Virtual Machine "willow_pink", to simulate state-of-art
Google processors.

Removal of cirq-rigetti

The Cirq-Rigetti subpackage has been removed after its deprecation in #7058.
For legacy code needs, please use the last release cirq-rigetti-1.5.0.

General code maintenance

Increased type-check coverage by adding type annotations to unit tests
(an ongoing effort). Updated annotations syntax to confirm to [PEP-585].
Activated ruff tool for fast code checking and linting. Deleted the
outdated maintenance tool pr_monitor and eliminated the use of Docker
in tools and tests.

cirq-core

Added CXSWAP and CZSWAP gates. Added transformers for manipulating
operation tags and for parameterizing tagged operations. Added support
for parameterized circuits in the merge-single-qubit-gates transformer.
Added a new implementation of parallel XEB accepting circuits instead of
single gates. Improved Randomized Benchmarking to reduce the size of
generated circuits. Simplified decomposition of controlled gates with
global phase. Added JSON serialization support for NoiseModel classes.
Extended the QASM import parser to understand more OpenQASM 2.0 gates.
Improved the output and speed of Quantum Shannon Decomposition.
Implemented support for adding tags to Cirq moments.
Enhanced apply_unitary and unitary to accept numpy matrices.

API change

Changed [CircuitOperation] to assume use_repetition_ids=False by default
(you can pass the explicit argument use_repetition_ids=True to restore
the previous behavior).

cirq-google

Added specifications for the new Quantum Virtual Machine (QVM) "willow_pink"
with updated demos in QVM notebooks. Improved serialization of Cirq objects
for Quantum Engine (QE) for better performance and to support more Cirq types.
Added classes to express analog qubit frequency and coupling experiments at QE.
Deprecated hard-coded default gate times in noise_properties_from_calibration.

cirq-ionq

Added support for expressing IonQ Pauli-exponential gates.
Fixed a bug in the computation of inverse MSGate.

cirq-web

Improved the cirq-web package layout to avoid installing the unnecessary
cirq_ts module.

Cirq v1.5.0 release

Summary

Added support for Python 3.13 and NumPy-2. Deprecated the Cirq-Rigetti
package, which was changed to an opt-in component of the Cirq suite.

Deprecation of Cirq-Rigetti

The Cirq-Rigetti subpackage has been deprecated. For more details or to provide
feedback, see #7058. Cirq-Rigetti needs to be installed explicitly using
pip install cirq-rigetti as it is not included with the cirq installation anymore.
Note that installation of Cirq-Rigetti requires a downgrade to Python 3.12 and NumPy-1.

cirq-core

Added BitMaskKeyCondition to provide multiqubit classical control conditions with bit
masks. Added support to concatenate parameter sweeps as a new sweep. Added preliminary
support for parsing OpenQASM-3. Improved MatrixGate decomposition to compensate for
global phase change. Added function for computing Rényi entropy. Added transformers for
cphase gauge transformation, simulation of depolarizing noise, and for performing
randomized measurement protocol. Added contrib utilities for readout error
benchmarking and an experimental workflow for Z-phase calibration of two-qubit gates.

API change

In next release the default value of the use_repetition_ids argument of the
[CircuitOperation] will change from True to False. Please pass an explicit
use_repetition_ids=True to preserve the current behavior of the code.

cirq-google

Enhanced serialization capability to support more circuit objects and parameter types
for the cirq-google service backend. Added support for stimcirq gates and operations.
Enhanced sweep proto messages with typed units and optional metadata.
Added support for custom device parameter overrides for circuit execution.

cirq-ionq

Added definitions for the IonQ ZZGate and for device gatesets AriaNativeGateset and
ForteNativeGateset. Added capability for circuit transpilation to native gatesets.

Cirq v1.4.0 release

Summary

Added support for Python 3.12 and increased minimum Python version to 3.10.

Removal of cirq-ft

The cirq-ft package introduced in 1.2.0 was deleted after its move to the
Qualtran repository at https://github.com/quantumlib/Qualtran.git.
Please use that repository for fault-tolerant resource estimation needs.

cirq-core

Added cirq.UniformSuperpositionGate for creating uniform superposition
from a subset of n-qubit basis states. Added transformer that implements
dynamical decoupling for idle moments in a circuit. Added cirq.UNIT_SWEEP
as an alias for the cirq.UnitSweep but with a constant-style name.
Exposed the Mølmer–Sørensen MSGate at the top level cirq namespace.

cirq-google

Removed functions create_calibration_program and create_batch_program.
Added tag class FSimViaModelTag to enable execution of the FSimGate
using polynomial model.

Cirq v1.3.0 release

Summary

Deprecation of cirq-ft

The newly created cirq-ft package (from 1.2.0) will be moving to its new home in the qualtran repository. Please pull from that repository to get all your fault-tolerant resource estimation goodness.

Qubit management

Two new qubit managers (GreedyQubitManager and SimpleQubitManager) can help manage creation and allocation of temporarily or borrowed ancilla qubits.

Performance improvements

Many minor performance improvements have been made over the past 6 months to help speed up troublesome corner cases, such as json serialization, transformers, circuit creation, and symbol resolution.

A classical simulator for simulating circuits without superposition (such as Toffoli, CNOT, X, SWAP, etc) has been added.

Cirq v1.2.0 release

Summary

This Cirq release focuses on making it easier to express and do resource estimations for Fault Tolerant Quantum Algorithms, with a number of high level improvement summarized as follows:

Improvements to Cirq-Core

  • Cirq protocols (eg: cirq.unitary) and simulators (eg: cirq.Simulator) now support gates that allocate new qubits as part of their decomposition
  • cirq.QubitManager is a new top-level abstraction that defines the interface for a qubit allocator/deallocator which can be used to manage ancilla qubits at the time of circuit construction.
  • cirq.decompose infrastructure is updated s.t. new composite gates can override the _decompose_with_context_ method to gain access to a cirq.DecompositionContext that contains options such as a cirq.QubitManager to help with allocating ancilla qubits at the time of circuit construction.

Cirq-FT: A new sub-package for Fault-Tolerant algorithms

Cirq-FT is a new sub-package for rapid prototyping and resource estimation of fault tolerant algorithms that extends Cirq. Some notable features include

  • A concept of qubit Register / Registers that make it easier for composite gates to express their signature in terms of named groups of logical qubits.
  • A cirq_ft.GateWithRegisters base class, which acts as a SHIM on top of the flat qubits API of cirq.Gate class and helps users define their composite gates using qubit registers.
  • New protocols, like cirq_ft.TComplexity, for macroscopic resource estimation.
  • New compilation transformers for mapping ancilla allocation / deallocation requests in a compute graph (eg: cirq circuit) to physical qubits, supporting both clean and dirty allocations.
  • A well-annotated and well-tested library of hierarchical gate decompositions which implements all the circuit primitives from Encoding Electronic Spectra in Quantum Circuits with Linear T Complexity. Table IV containing resource estimates of circuits with ~10^10 T-gates can be reproduced in under a minute demonstrating the scalability of the framework.

Other notable changes

  • Dropped support for Python 3.7 and Python 3.8 and added support for Python 3.11
  • Performance improvements for parameter resolution and a new __cirq_debug__ flag that provides an option to disable validations at the time of circuit construction.

Cirq v1.1.0 release

Summary

This Cirq release focuses on tracking and improving performance of key workflows like circuit construction, parameter resolution etc. The release also adds a new transformers framework for qubit routing and provides an efficient implementation of the qubit routing algorithm described in arXiv:1902.08091 [quant-ph]

As part of this release, we have also published our new backwards compatibility guidelines.

What's new

Cirq has officially left alpha and is v1.0. With this release comes new policies on API stability as well as functionality gaurantees for the long term. Along with some minor bug fixes and tweaks, this release focuses on stabilizing the APIs within cirq-core. With cirq-core we intend to follow along with semver and only make breaking changes with moves to new major versions. For the vendor packages we plan to continue to allow developers to iterate at speed and will do best effort on ensuring any API changes come with as little friction as possible. For all the details on this policy please see: release.md.

To make this upgrade as smooth as possible, we recommend first upgrading your installation to Cirq v0.15 to surface any deprecation warnings or upcoming breakages you might experience, once those are resolved, you can safely install Cirq v1.0.0.

Thank you all so much for your hard work.
