Optimize qid comparisons #6386

Closed maffoo closed 9 months ago

maffoo commented 9 months ago

Qid comparison turns out to be a very common operation when manipulating circuits, for example when computing the hash of a moment we sort operations by qubits in order to have a canonical order for hashing. Here we optimize the comparison of common qid types for grid, line, and named qubits.
