supergrad.time_evolution.pulseshape.PulseTrapezoid

class supergrad.time_evolution.pulseshape.PulseTrapezoid(length=False, amp=None, delay=0, modulate_wave=False, name: str = 'pulse_trapezoid', **kwargs)

The trapezoid pulse.

Parameters:

• length – the length of pulse

• amp – the amplitude of pulse

• delay – time delay for waiting other gate operations

• modulate_wave (bool) – True for generate modulated sine wave

• name – module name

amp

max amplitude of the trapezoid

t_ramp

time of the rising and falling edges

t_plateau

the holding time of the plateau of the waveform

length

the length of pulse shape

__init__(length=False, amp=None, delay=0, modulate_wave=False, name: str = 'pulse_trapezoid', **kwargs)

Initializes the current module with the given name.

Subclasses should call this constructor before creating other modules or variables such that those modules are named correctly.

Parameters:

name – An optional string name for the class. Must be a valid Python identifier. If name is not provided then the class name for the current instance is converted to lower_snake_case and used instead.

Methods

__init__([length, amp, delay, ...])	Initializes the current module with the given name.
create_envelope_pulse(t[, args])	Create envelope pulse shape for various gate operations.
create_pulse(t[, args])	Create desired pulse shape for various gate operations.
params_dict()	Returns parameters keyed by name for this module and submodules.
state_dict()	Returns state keyed by name for this module and submodules.

Attributes

pulse_endtime

The time of last pulse frame
