2.6. The ConstantPulseTemplate

The ConstantPulseTemplate(or short ConstantPT) can be used to define pulse templates with all channels a constant value. The template is easy to define and allows backends to optimize the waveforms on an AWG.

%matplotlib inline
from qupulse.pulses import ConstantPT

constant_template = ConstantPT(10, {'A': 1., 'B': .2})

print(constant_template.defined_channels)
print(constant_template.integral)

{'A', 'B'}
{'A': Expression('10.0000000000000'), 'B': Expression('2.00000000000000')}

The pulse template has two channels.

from qupulse.pulses.plotting import plot

_ = plot(constant_template, sample_rate=100)
