This new release of Cirq v1.1, a software library for quantum computing supported by Google, focuses on improving the performance of critical workflows such as circuit construction and parameter resolution. It also introduces a new transformer framework for qubit routing and efficiently implements a qubit routing algorithm. The release includes updates to support multi-qubit measurements in the deferred measurement transformer, changes to avoid warnings on complex-to-float conversion, and the addition of new features such as Observables and PauliStrings. In addition, the release includes various bug fixes and improvements to the documentation and code.
Here is a selection of highlights:
- The addition of a transformers framework for qubit routing, which includes a new qubit routing algorithm and several new top-level objects in the
cirq-coremodule, includingRoutingSwapTag,AbstractInitialMapper,HardCodedInitialMapper,LineInitialMapper,MappingManager,RouteCQC, androuted_circuit_with_mapping. - Support for multi-qubit measurements in the deferred measurement transformer.
- Changes to avoid warnings on complex-to-float conversion.
- The addition of Observables and PauliStrings.
- Improvements to the documentation, including updates to the getting started tutorial and the addition of QVM pages.
- Various bug fixes and code improvements, including adding the
{Frozen}Circuit.from_momentsmethod to construct circuits using moments, changes to the mapping manager to use the Floyd Warshall algorithm, and improvements to the unit testing for routed circuits.
