This is the README file for the Precise certification of a qubit space. To run the test yourself, you have to register at quantum-computing.ibm.com. The scripts can be run either inside the Quantum Lab, available for the registered users, in a Jupyter notebook (jupyter.org) or remote by any Python interpreter (www.python.org) after submitting your token by IBMQ.save_account(token) The token is a long string of characters, you obtain from IBM after registering. The scripts in Python are: 1) dim-wit.py to run the test I and II. 2) dim-wit-par.py to run the parameterized test 3) dim-an-limlag.py, dim-par-anp.py to analyze the data (it does not need IBM account) 4) Job.py a collection of functions used in the above scripts The data are in the zip files for each job in .csv format. The columns are: number of 0s, number of 1s, angle, preparation, measurement, and optionally parameter, for each circuit, data.json contains the global description. wyniki {Polish} = results {English} Have fun!
