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.
