Exporter

class Exporter(includes=('stdgates.inc'), basis_gates=('U'), disable_constants=False, alias_classical_registers=False, indent=' ')

Bases: object

QASM3 expoter main class.

Parameters

• includes (Sequence[str]) – the filenames that should be emitted as includes. These files will be parsed for gates, and any objects dumped from this exporter will use those definitions where possible.
• basis_gates (Sequence[str]) – the basic defined gate set of the backend.
• disable_constants (bool) – if True, always emit floating-point constants for numeric parameter values. If False (the default), then values close to multiples of QASM 3 constants (pi, euler, and tau) will be emitted in terms of those constants instead, potentially improving accuracy in the output.
• alias_classical_registers (bool) – If True, then classical bit and classical register declarations will look similar to quantum declarations, where the whole set of bits will be declared in a flat array, and the registers will just be aliases to collections of these bits. This is inefficient for running OpenQASM 3 programs, however, and may not be well supported on backends. Instead, the default behaviour of False means that individual classical registers will gain their own bit[size] register; declarations, and loose Clbits will go onto their own declaration. In this form, each Clbit must be in either zero or one ClassicalRegisters.
• indent (str) – the indentation string to use for each level within an indented block. Can be set to the empty string to disable indentation.
