Study makes a quantum entanglement leap

A German team takes a crucial step in exploiting a long-distance phenomenon that even Einstein once called ‘spooky.’

Some scientists have likened it to voodoo, while Albert Einstein called it just plain “spooky.”

In the bizarre realm of quantum mechanics, entanglement is the phenomenon in which two seemingly distinct particles control each other in ways that defy common physical sense. For instance, when an atom located in Beijing is measured by an observer, it will exhibit the exact opposite qualities of its entangled counterpart in Boston…
