Quantum Entanglement Can Reach Into the Past
Spooky quantum entanglement just got spookier. Entanglement is a weird state where two particles remain intimately connected, even when separated over vast distances, like two die that must always show the same numbers when rolled. For the first time, scientists have entangled particles after they’ve been measured and may no longer even exist.
If that sounds baffling, even the researchers agree it’s a bit “radical,” in a paper reporting the experiment published online in the journal Nature Physics. Essentially, the scientists showed that future actions may influence past events, at least when it comes to the messy, mind-bending world of quantum physics.
