cirq.optimizers.EjectZ(
    tolerance: float = 0.0,
    eject_parameterized: bool = False
) -> None

As the Z gates get pushed they may absorb other Z gates, get absorbed into measurements, cross CZ gates, cross W gates (by phasing them), etc.

Args
tolerance	Maximum absolute error tolerance. The optimization is permitted to simply drop negligible combinations of Z gates, with a threshold determined by this tolerance.
eject_parameterized	If True, the optimization will attempt to eject parameterized Z gates as well. This may result in other gates parameterized by symbolic expressions.
