Qibocal

Qibocal provides calibration protocols using Qibo and Qibolab.

Qibocal key features:

• Declarative inputs using runcard.

• Generation of a report.

Documentation

Qibocal documentation is available here.

Note

Qibocal main contains some breaking changes compared to 0.1 versions. A small guide to make the transition as smooth as possible can be found here.

Installation

The package can be installed by source:

git clone https://github.com/qiboteam/qibocal.git
cd qibocal
pip install .

Developer instructions

For development make sure to install the package using poetry and to install the pre-commit hooks:

git clone https://github.com/qiboteam/qibocal.git
cd qibocal
poetry install
pre-commit install

Minimal working example

Here is an example on how to run a Rabi experiment in Qibocal.

from qibocal import create_calibration_platform
from qibocal.protocols import rabi_amplitude

# create platform
platform = create_calibration_platform("qubit")

# define qubits where the protocols will be executed
targets = [0]

# define protocol parameters
params = rabi_amplitude.parameters_type.load(dict(
        min_amp=0.01,
        max_amp=0.2,
        step_amp=0.02,
        nshots=2000,
        pulse_length=40,
        ))

# acquire
platform.connect()
data, acquisition_time = rabi_amplitude.acquisition(
                                                    params=params,
                                                    platform=platform,
                                                    targets=targets
                                                    )
platform.disconnect()

# post-processing
results, fit_time = rabi_amplitude.fit(data=data)

# visualize the results
plots, table = rabi_amplitude.report(data=data, results=results, target=target[0])
plots[0].show()

The table is written in HTML and can be visualized in Python with

from IPython import display
display.HTML(table)

Running a protocol through a runcard

The same experiment can also be run using the following yaml file

platform: qubit
targets: [0]
actions:
- id: rabi
  operation: rabi_amplitude
  parameters:
    min_amp: 0.01
    max_amp: 0.2
    step_amp: 0.02
    nshots: 2000
    pulse_length: 40

To run the protocol Qibocal uses the qq run command

qq run <runcard> -o <output_folder>

if <output_folder> is specified, the results will be saved in it, otherwise qq will automatically create a default folder containing the current date and the username.

Uploading reports to server

In order to upload the report to a centralized server, send to the server administrators your public ssh key (from the machine(s) you are planning to upload the report) and then use the qq upload <output_folder> command. This program will upload your report to the server and generate an unique URL.
