pack_register_to_int(var, size: int)[source][source]

Pack classical bits into a single integer (LSB = bit index 0).

Packing follows the wired QUA variable shape: arrays are indexed as var[i]; scalars are cast directly (only valid when size == 1).

Parameters:

  • var – Compiler-owned QUA bool scalar or bool array from result_program.

  • size – Number of bits to pack from var.

Raises:

ValueError – If size is not positive, or a multi-bit output is wired to a scalar QUA variable.
