cirq.eject_z

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 PhasedXPowGate (aka W) gates (by phasing them), etc.

circuit Input circuit to transform.
context cirq.TransformerContext storing common configurable options for transformers.
atol 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.
