The authors delve into the dynamics of vortex electrons as they transition from a vacuum into a magnetic field and propagate within it. They show that nonstationary Laguerre-Gaussian states offer a genuine description of the electron motion, revealing oscillations in the electrons’ root-mean-square radius, which is significantly larger than expected.

The work challenges the concept of “classical independence” between physical systems by demonstrating that within quantum theory two systems can affect each other despite no observable changes, unveiling the interconnected nature of the quantum world. The findings also unveil potential applications for device-independent certification of quantum states and measurements.
