Pulse

class Pulse(start, end, frequency, complex_envelope, driving_field=None)

Represents a single pulse.

The class defines a finite-duration pulse characterized by a constant frequency and a specified complex envelope. It can be attached to a driving field to specify its time-dependent behavior.

Note

Pulse is a low-level object representing a pulse or a pulse fragment (e.g. rising edge of a smooth pulse). To add pulses to driving fields, use the appropriate add_..._pulse() methods of the corresponding LinearDrivingField or CircularDrivingField instances.

Initialize a pulse.

Parameters:

• start (float) – Trigger (start) time of the pulse (in \(\mu\text{s}\)).

• end (float) – End time of the pulse (in \(\mu\text{s}\)).

• frequency (float) – Frequency of the pulse (in \(\text{MHz}\)).

• complex_envelope (complex | Callable) – Complex envelope of the pulse. It can be a complex number or a callable returning a complex-valued function (in \(\text{T}\)).

• driving_field (BaseDrivingField | None) – Driving field which the pulse is attached to.

Attributes

abs_frequency	Absolute value of the pulse frequency (in \(\text{MHz}\)).
complex_envelope	Complex envelope of the pulse (in \(\text{T}\)).
driving_field	Driving field which the pulse is attached to.
end	End time of the pulse (in \(\mu\text{s}\)).
frequency	Frequency of the pulse (in \(\text{MHz}\)).
is_constant_envelope	Returns whether the pulse has a constant envelope or not.
signal	Return this pulse as a Simphony Signal with its carrier and envelope.
start	Trigger (start) time of the pulse (in \(\mu\text{s}\)).
