Researchers violate Bell’s inequality with an atom and a photon

Researchers at the University of Michigan have reported the first Bell’s inequality violation measurement of a single entangled atom-photon pair.

Entanglement is a fundamental yet mysterious feature of quantum physics, said David Moehring, a physics graduate student who co-authored the paper entitled, “Experimental Bell Inequality Violation with an Atom and a Photon,” which appeared in Physical Review Letters this month.
