save_results

qililab.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.
