save_results

qililab.result.save_results(results, loops, data_path, name=None)

Save the given results and the platform.

A timestamp is used to create a folder to save the data. The data will be saved within the file located in: path/yearmonthday/hourminutesecond_name/results.h5.

Parameters:

• results (np.ndarray) – Array containing the results to be saved.

• loops (dict) – A dictionary containing all the loops used in an experiment. The keys are used to identify the loop and the values of the dictionary correspond to the values of the loop.

• data_path (str) – Path to the main data directory.

• name (str, optional) – Name of the experiment. If given, the name is added to the name of the folder. Defaults to None.

Returns:

Path to folder where the results are saved.

Return type:

str

Examples

Imagine you want to run the following sequence:

circuit = Circuit(1)
circuit.add(gates.X(0))
circuit.add(gates.M(0))

results = []
gain_values = np.arange(0, 1, step=0.01)
for gain in gain_values:
    platform.set_parameter(alias="drive_q0", parameter=ql.Parameter.GAIN, value=gain)
    result = platform.execute(circuit, num_avg=1000, repetition_duration=200000)
    results.append(result)

results = np.hstack(results)

You can then save the results by running:

loops = {"drive_q0_gain": gain_values}
ql.save_results(results=results, loops=loops, path="data/", name="rabi")

Imagine we call the cell above on August 22nd of 2023, at 15:14:12. The file will then be saved to: data/20230822/151412_rabi/results.h5.
