The phenomenon of quantum nonlocality defies our everyday intuition. It shows the strong correlations between several quantum particles some of which change their state instantaneously when the others are measured, regardless of the distance between them. While this phenomenon has been confirmed for slow moving particles, it has been debated whether nonlocality is preserved when particles move very fast at velocities close to the speed of light, and even more so when those velocities are quantum mechanically indefinite.

This could be a breakthrough for future magnetic materials, and another step towards spintronics. An international group led by Empa researchers recently published the results in the journal “Angewandte Chemie”.
