qiskit.pulse.library.sech_deriv

sech_deriv(duration, amp, sigma, name=None)

Generates unnormalized sech derivative Waveform.

For $A=$ amp, $\sigma=$ sigma, and center $\mu=$ duration/2, applies the midpoint sampling strategy to generate a discrete pulse sampled from the continuous function:

i.e. the derivative of $\text{sech}$.

Parameters

• duration (int) – Duration of pulse. Must be greater than zero.
• amp (complex) – Pulse amplitude at center.
• sigma (float) – Width (standard deviation) of pulse.
• name (Optional[str]) – Name of pulse.

Return type

Waveform
