Community-contributed workflows

Some additional workflows in Qubex are provided as community-contributed functions under qubex.contrib rather than as core Experiment methods.

This page is mainly a migration note for existing users. If an older notebook or script calls an Experiment helper that is no longer available there, use the corresponding contrib function instead and pass exp as the first argument.

from qubex import contrib

Moved APIs

Use this mapping when updating older notebooks or scripts:

Old call on `exp`	New contrib function
`exp.measure_cr_crosstalk(...)`	`contrib.measure_cr_crosstalk(exp, ...)`
`exp.cr_crosstalk_hamiltonian_tomography(...)`	`contrib.cr_crosstalk_hamiltonian_tomography(exp, ...)`
`exp._simultaneous_measurement_coherence(...)`	`contrib.simultaneous_coherence_measurement(exp, ...)`
`exp._stark_t1_experiment(...)`	`contrib.stark_t1_experiment(exp, ...)`
`exp._stark_ramsey_experiment(...)`	`contrib.stark_ramsey_experiment(exp, ...)`
`exp.purity_benchmarking(...)`	`contrib.purity_benchmarking(exp, ...)`
`exp.interleaved_purity_benchmarking(...)`	`contrib.interleaved_purity_benchmarking(exp, ...)`

Simultaneous coherence

import numpy as np
from qubex import contrib

results = contrib.simultaneous_coherence_measurement(
    exp,
    targets=[Q0, Q1],
    time_range=np.arange(0, 20_001, 1000),
    n_shots=1024,
)

t1_result = results["T1"]
t1_result.plot()

Stark-driven characterization

from qubex import contrib

stark_result = contrib.stark_t1_experiment(
    exp,
    targets=[Q0],
    stark_detuning=0.05,
    stark_amplitude=0.1,
    n_shots=1024,
)

stark_result.plot()

Purity benchmarking

from qubex import contrib

pb_result = contrib.purity_benchmarking(
    exp,
    targets=[Q0],
    n_shots=1024,
)

print(pb_result)
