Entanglement on a Chip: Breakthrough Promises Secure Communications and Faster Computers

Unlike Bilbo’s magic ring, which entangles human hearts, engineers have created a new micro-ring that entangles individual particles of light, an important first step in a whole host of new technologies.
Entanglement – the instantaneous connection between two particles no matter their distance apart – is one of the most intriguing and promising phenomena in all of physics. Properly harnessed, entangled photons could revolutionize computing, communications, and cyber security.
