Illustration of the experiment (IMAGE) Technion-Israel Institute of Technology Caption A single free electron propagates above the special layered structure that the researchers engineered, only a few tens of nanometers above it. During its movement, the electron emits discrete packets of radiation called "photons". Between the electron and the photons it emitted, a connection of "quantum entanglement" is formed.
