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.

v1.2.0

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

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.

v1.0.0

506ef08

Cirq v1.0.0

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.

v0.15.0

f904a09

Cirq v0.15.0

Cirq v0.15.0 release

Summary

This Cirq release focuses on fine tuning user APIs and library organization, with no new major feature additions. This release features lots of deprecations and long standing bug fixes in anticipation of the upcoming Cirq 1.0 release as well as a few refactors. This release fixes over 150 oustanding issues in Cirq and stabilizes many of the rough edges in the library. In upgrading to 1.0 it is recommended to first upgrade to this version to receive deprecation warnings for any changed functionality before moving to Cirq 1.0
