The experiment was carried out at Ben-Gurion University using clouds of rubidium atoms cooled to just above absolute zero and manipulated close to the surface of a specially designed atom chip.

The experimental team, including PhD student Or Dobkowski, first used microwave pulses to put the ultracold atoms into a quantum superposition, effectively allowing each atom to travel along two different paths at ...
