deltakit.circuit.NoiseLayer.approx_equals

NoiseLayer.approx_equals(other: object, *, rel_tol: float = 1e-09, abs_tol: float = 0) → bool

Determine whether two noise layers are approximately equal within a tolerance. The tolerance accounts for small differences in the error probabilities of noise channels. All other properties must be equal.

Parameters:

• other (object) – The other object to which to compare this gate layer.

• rel_tol (float) – The allowed relative difference between the error probabilities of two noise channels, if this is larger than that calculated from abs_tol. Has the same meaning as in math.isclose. By default, 1e-9.

• abs_tol (float, optional) – The allowed absolute difference between the error probabilities of two noise channels, if this is larger than that calculated from rel_tol. Has the same meaning as in math.isclose. By default, 0.0.

Returns:

Whether the two noise layers are approximately equal.

Return type:

bool
