QGL2 RabiAmp


Compiling a QGL2 RabiAmp and plotting the output


In [22]:
# Using phase=0, amp from 0 -> 1 stepping by 0.1

Imports


In [23]:
from pyqgl2.main import compile_function, qgl2_compile_to_hardware
from pyqgl2.test_cl import create_default_channelLibrary
from pyqgl2.qreg import QRegister
from QGL import plot_pulse_files, ChannelLibrary
import numpy as np

Create a test ChannelLibrary


In [24]:
create_default_channelLibrary(True, True)
# Alternatively could load an existing library, or create one here; see the 'AllXY' notebook

Create needed qubit(s)


In [25]:
# For QGL2, use a QRegister, not a QGL Qubit
q = QRegister(1)

Compile to QGL1


In [26]:
# Insert proper path to QGL2 source and name of qgl2main if not so marked
# Here we compile the named function in the named file from QGL2 to QGL1 and return the new functio

qgl1MainFunc = compile_function("../src/python/qgl2/basic_sequences/Rabi.py", "RabiAmp", (q, rAmpAmps, 0), saveOutput=True)
