Gaussian

class Gaussian(duration, amp, sigma, name=None)

Bases: qiskit.pulse.library.parametric_pulses.ParametricPulse

A truncated pulse envelope shaped according to the Gaussian function whose mean is centered at the center of the pulse (duration / 2):

\[f(x) = amp * exp( -(1/2) * (x - duration/2)^2 / sigma^2) ) , 0 <= x < duration\]

Initialize the gaussian pulse.

Parameters

• duration (Union[int, ParameterExpression]) – Pulse length in terms of the the sampling period dt.

• amp (Union[complex, ParameterExpression]) – The amplitude of the Gaussian envelope.

• sigma (Union[float, ParameterExpression]) – A measure of how wide or narrow the Gaussian peak is; described mathematically in the class docstring.

• name (Optional[str]) – Display name for this pulse envelope.

Methods

assign	Assign one parameter to a value, which can either be numeric or another parameter expression.
assign_parameters	Return a new ParametricPulse with parameters assigned.
draw	Plot the interpolated envelope of pulse.
get_waveform	Return a Waveform with samples filled according to the formula that the pulse represents and the parameter values it contains.
