Indeed that's something we were considering when looking at upgrading the Pauli measurement preprocessing. If we add this we then have multiple ways of defining Pauli measurement that will have to be delt with. No strong opinion about this, open to discussion ! |

This commit introduces a new method `is_pauli` on `M` commands, which returns a pair `(axis, sign)` if the measure is Pauli, and `None` otherwise. This method takes an optional parameter `precision` ($\rho$, default: `1e-6`): a measure is considered to be Pauli if the angle is in an interval $[- \rho + k \cdot \frac \pi 2; \rho + k \cdot \frac \pi 2]$, addressing the precision problem raised in TeamGraphix#181. `axis` is computed by using the `cos` and `sin` definitions of `pauli.py`, solving the inconsistency bug reported in TeamGraphix#188. This commit introduces a new `Sign` class to make code manipulating `Plus` and `Minus` to be more readable than when using `bool`.

Currently, Pauli measurements are determined by checking the angle mod$2\pi$ , with non-zero possiblity of incorrect determination of Pauli-measured nodes by numerical errors. I believe it's natural to incorporate Pauli measurements as
X,Y, andZplanes. See also implementation of rust-based flow-finding routines in TeamGraphix/fastflow#3.The text was updated successfully, but these errors were encountered:
