This contribution presents The Sound of Entanglement, a project at the intersection of quantum physics, music, and visual art. At its core lies a Bell experiment setup, where polarization-entangled photon pairs are generated through spontaneous parametric down-conversion in a β-BBO crystal. The experiment acts as a quantum conductor, utilizing the quantum correlations between the photons to coordinate and influence the choices of live musicians in real-time, creating a performance guided by principles beyond classical physics.

This work seeks to make these abstract concepts more accessible and engaging to broader audiences by transforming them into tangible, sensory experiences. By combining live music with a dynamic light show, both controlled by the experiment, this project illustrates how advancements in technology, like those shaping the second quantum revolution, can redefine artistic expression and bridge the gap between science and art.
