Quantum Entanglement Experiments Expand to Include 8 Photons

The quantum phenomenon known as entanglement keeps spreading its arms to hold ever more particles in its spooky embrace. Quantum entanglement is an effect through which multiple particles share correlated properties—across arbitrarily large distances—that snap into place instantaneously. For instance, a pair of entangled photons in different locations might be joined by their polarizations, a [...]

George and John’s Excellent Adventures in Quantum Entanglement [Video]

Simply put, bottomlessly deep: that is the definition of a great discovery in science. From the principle of relativity to evolution by natural selection, the concepts that govern our world are actually not that hard to state. What they mean and what they imply—well, that’s another matter. And so it is with quantum entanglement. One [...]
