Backend and utilities

See the Backend & Utilities guide for execution modes and hybrid embedding. For the measurement-output locality model, see Measurement outputs.

Backends

QMBackend(machine[, channel_mapping, ...])	Qiskit backend for Quantum Machines (QuAM).
FluxTunableTransmonBackend(machine[, qmm, name])	Reference QMBackend for flux-tunable transmon QuAM machines.
QMInstructionProperties([duration, error, ...])	Qiskit instruction properties enriched with a QUA pulse macro.

Circuit compilation and measurement outputs

QuaCircuitCompilation(compilation_result, ...)	Wrapper around CompilationResult with ergonomic measurement outputs.
MeasurementOutcomeTable(fields, name)	Local-only grouping of measurement output fields.

MeasurementRegisterField(name, length, *[, ...])

One classical register (or loose bit) wired from a qm-qasm compilation result.

Functions

add_basic_macros(backend[, reset_type])	Populate a QuAM machine with standard gate-level macros.
assign_struct_with_table(struct, table)	QUA macro: copy declared parameter values into a matching OPNIC struct.
get_measurement_outcomes(qc, result[, ...])	Wire classical measurement outcomes from an embedded circuit into QUA variables.
get_qua_script(backend, circuit[, param_table])	Compile a circuit to QUA and return the running QUA script as a string.
dump_qua_script(backend, circuit[, path, ...])	Compile a circuit to QUA and write the running QUA script to a file.
pack_register_to_int(var, size)	Pack classical bits into a single integer (LSB = bit index 0).
