The Big Bell Test

screen-shot-2016-11-15-at-17-13-33

The BIG Bell Test (BBT) is a worldwide project to bring human unpredictability (randomness) to cutting-edge physics experiments. It may be surprising, but there are aspects of physical reality that can only be understood by asking unpredictable questions of nature. The most famous experiment of this kind is the Bell test. In the BBT, laboratories around the world (see map) will prepare entangled quantum particles: electrons, photons, atoms, and superconductors. Through the Internet, an army of participants, the Bellsters, will shower these particles with unpredictable, high-speed “questions” (measurements, in fact). Together, we will perform unique quantum physics experiments, including the first human-driven Bell test.

The experiments will all take place on Wednesday, November 30th and everyone can contribute by going to the project website and playing the games proposed.

Claudia Benedetti, Marco Genoni and Stefano Olivares from the Applied Quantum Mechanics Group will give an introductory seminar aimed at high-school and university students on Tuesday, November 29th at 14:30 in Aula A of the Physics Department.

Here are the slides of the seminar:
