cirq.EjectZ

THIS CLASS IS DEPRECATED.

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

Used in the notebooks

Used in the tutorials

IT WILL BE REMOVED IN cirq v1.0.

Use cirq.eject_z instead.

Pushes Z gates towards the end of the circuit.

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.

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.
