pyquil.quantum_processor.transformers package

Various transformers for quantum processor ISA representations.

exception pyquil.quantum_processor.transformers.GraphGateError[source]

Bases: ValueError

Signals an error when creating a CompilerISA from an nx.Graph.

This may raise as a consequence of unsupported gates.

exception pyquil.quantum_processor.transformers.QCSISAParseError[source]

Bases: ValueError

Signals an error when creating a CompilerISA due to the operators in the QCS InstructionSetArchitecture.

This may raise as a consequence of unsupported gates as well as missing nodes or edges.

pyquil.quantum_processor.transformers.compiler_isa_to_graph(compiler_isa: CompilerISA) → Graph[source]

Generate an nx.Graph based on the qubits and edges of any CompilerISA.

pyquil.quantum_processor.transformers.graph_to_compiler_isa(graph: Graph, gates_1q: list[str] | None = None, gates_2q: list[str] | None = None) → CompilerISA[source]

Generate an CompilerISA object from a NetworkX graph and list of 1Q and 2Q gates.

May raise GraphGateError if the specified gates are not supported.

Parameters:

  • graph – The graph topology of the quantum_processor.

  • gates_1q – A list of 1Q gate names to be made available for all qubits in the quantum_processor. Defaults to DEFAULT_1Q_GATES.

  • gates_2q – A list of 2Q gate names to be made available for all edges in the quantum_processor. Defaults to DEFAULT_2Q_GATES.

pyquil.quantum_processor.transformers.qcs_isa_to_compiler_isa(isa: InstructionSetArchitecture) → CompilerISA[source]

Transform a QCS InstructionSetArchitecture into a CompilerISA.

pyquil.quantum_processor.transformers.qcs_isa_to_graph(isa: InstructionSetArchitecture) → Graph[source]

Convert a QCS Instruction Set Architecture to a NetworkX graph.
