Usage

Examples can be found in python/examples.

import matplotlib.pyplot as plt

from bosing import Barrier, Channel, Hann, Play, Stack, generate_waveforms

channels = {"xy": Channel(30e6, 2e9, 1000)}
shapes = {"hann": Hann()}
schedule = Stack(duration=500e-9).with_children(
    Play(
        channel_id="xy",
        shape_id="hann",
        amplitude=0.3,
        width=100e-9,
        plateau=200e-9,
    ),
    Barrier(duration=10e-9),
)
result = generate_waveforms(channels, shapes, schedule)
w = result["xy"]
plt.plot(w[0], label="I")
plt.plot(w[1], label="Q")
plt.legend()
plt.show()

If you want to post-process waveforms outside of bosing, you can generate a deduplicated list of envelopes and compact pulse instructions:

import numpy as np

from bosing import Barrier, Channel, Hann, Play, Stack, generate_envelopes_and_instructions

length = 1000
channels = {"xy": Channel(30e6, 2e9, length)}
shapes = {"hann": Hann()}
schedule = Stack(duration=500e-9).with_children(
    Play(channel_id="xy", shape_id="hann", amplitude=0.3, width=100e-9, plateau=200e-9),
    Barrier(duration=10e-9),
)

envelopes, instructions = generate_envelopes_and_instructions(channels, shapes, schedule)
inst0 = instructions["xy"][0]
env0 = envelopes[inst0.env_id]
assert env0.dtype == np.float64
