Gaussian

class qiskit.pulse.library.Gaussian(duration, amp, sigma, angle=0.0, name=None, limit_amplitude=None)

Bases: object

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

where $f'(x)$ is the gaussian waveform without lifting or amplitude scaling, and $\text{A} = \text{amp} \times \exp\left(i\times\text{angle}\right)$.

Parameters

• duration – Pulse length in terms of the sampling period dt.
• amp – The magnitude of the amplitude of the Gaussian envelope.
• sigma – A measure of how wide or narrow the Gaussian peak is; described mathematically in the class docstring.
• angle – The angle of the complex amplitude of the Gaussian envelope. Default value 0.
• name – Display name for this pulse envelope.
• limit_amplitude – If True, then limit the amplitude of the waveform to 1. The default is True and the amplitude is constrained to 1.
