A new experiment confirms that photons passing through a cloud of atoms can spend a negative amount of time there, and the atoms themselves are the ones saying so.
It has been known since the 1960s that the quantum statistical properties of light have a role in optical processes 3. For example, when more than one photon is required to ionize an atom, random ...
TL;DR: This experiment may not revolutionize telecommunications, but it highlights how accessible these concepts have become outside traditional research labs. Using nothing more than an iPad, a solar ...
