Quantum physics concerns infinitely small scales (including the interactions between atoms and particles), for which the laws of classical physics are no longer sufficient to describe the different phenomena at play. Quantum entanglement is the phenomenon in which two particles (or groups of particles) form a linked system, with quantum states depending on each other, regardless of the distance between them. Recently, researchers have been able to establish a link between quantum entanglement and quantum criticality (a phenomenon linked to quantum fluctuations), by entangling billions of billions of electrons through a metallic film ...
