pyquil.quantum_processor.qcs module

An implementation of AbstractQuantumProcessor based on an InstructionSetArchitecture returned from the QCS API.

class pyquil.quantum_processor.qcs.QCSQuantumProcessor(quantum_processor_id: str, isa: InstructionSetArchitecture, noise_model: NoiseModel | None = None)

Bases: AbstractQuantumProcessor

An AbstractQuantumProcessor initialized with an InstructionSetArchitecture returned from the QCS API.

Notably, this class is able to serialize a CompilerISA based on the architecture instructions.

Initialize a new QCSQuantumProcessor.

Parameters:

• quantum_processor_id – The id of the quantum processor.

• isa – The QCS API InstructionSetArchitecture.

• noise_model – An optional NoiseModel for configuring a noisy quantum_processor on the QVM.

noise_model: NoiseModel | None

quantum_processor_id: str

qubit_topology() → Graph

Return the qubit topology as a NetworkX graph.

qubits() → list[int]

Return the qubits in the quantum_processor topology.

to_compiler_isa() → CompilerISA

Return a CompilerISA representation of the quantum_processor’s InstructionSetArchitecture.

pyquil.quantum_processor.qcs.get_qcs_quantum_processor(quantum_processor_id: str, client_configuration: QCSClient | None = None, timeout: float = 10.0) → QCSQuantumProcessor

Retrieve an instruction set architecture for the specified QPU ID and initialize a QCSQuantumProcessor with it.

Parameters:

• quantum_processor_id – QCS ID for the quantum processor.

• timeout – Time limit for request, in seconds.

• client_configuration – Optional client configuration. If none is provided, a default one will be loaded.

Returns:

A QCSQuantumProcessor with the requested ISA.
