The scientific community is abuzz. On November 30, 2016, twelve different labs around the world will simultaneously conduct a series of quantum physics experiments.

The Physics Department at Sapienza University, directed by Professor Paolo Mataloni, is the only Italian partner of the Big Bell Test and will hold an experiment in the Quantum Information Lab of the Physics Department, managed by Prof. Fabio Sciarrino.

While a century has passed since the rise of quantum physics, scientists are still battling with a long series of mysteries presented by the study of atomic and sub-atomic worlds and their minuscule particles that interact at enormous distances, and objects that behave differently when they are not observed. Quantum physics previsions pay no attention to common sense.

Morgan Mitchell, the project coordinator and a physicist at the Institute of Photonic Sciences in Barcelona, explains: “The fundamental idea of the experiment is that if nature discovered what we were about to ask it, it could deceive us by preparing a custom-tailored answer. In this context, scientists making many independent decisions represent a precious resource. It’s the only way to make unpredictable questions, no matter what secrets nature tries to hide from us.”

Thus, the idea of a running a worldwide experiment involving a vast number of random participants using the Internet. In this way, for the first time, human unpredictability will play a key role in a series of quantum physics experiments, some of which have never been organised before.

Participating scientists around the world will be asked to participate in an on-line videogame (www.thebigbelltest.org) and create random sequences of 0s and 1s. These bits will be transmitted to the labs to determine the “questions” or what measurements to make on quantum objects, such as atoms, photons and super conductors.

 “Fortunately, the Sapienza Physics Department is involved in this initiative. It is the only institution that will be running two experiments: one in Rome, managed by Fabio Sciarrino, and one at the Concepcion University in Chile that involves four countries (Chile, Spain, Sweden and Italy),” points out Professor Paolo Mataloni.

“The experiment at the Sapienza Quantum Information Lab will involve four photons, entangled  in paris,” entangled in twos,” explains Professor Sciarrino. “Our objective is to observe quantum non-locality in a network of various nodes that are remotely controlled by the randomness generated by Big Bell Platform”.

The system will be operative for 24 hours on November 30 and its results will be published on Decmber 1, 2016.
