#QUANTUM: "Internet to Communicate by Entanglement"

The realization of a quantum Internet got one step closer when entanglement was recently demonstrated as a viable method to broadcast or copy information to many other network nodes—or users—simultaneously. Look for advances in quantum computing leading to innovative uses on the Internet over the next eight to 12 years. R. Colin Johnson, Kyoto Prize Fellow @NextGenLog


Massive hardware cools and isolates the nodes of Caltech's seminal quantum network (source: Nara Cavalcanti).

Here is what my Smarter Technology story says about quantum computing: Secure eavesdrop-proof communications using quantum-key distribution are already available over optical gateways between two parties, but now a possible new quantum Internet could be enabled by teleporting the same information to multiple nodes using entanglement—what Einstein called "spooky action at a distance"—thereby allowing secure broadcasts to copy identical information to multiple nodes on a future quantum Internet...
