"JB immediately tossed me in a corner of the restaurant with Sergey Brin and Larry Page, who grilled me on the potential applications of quantum computation. They were shockingly knowledgeable on the subject and quickly pushed me like a novice sumo wrestler to edge of the ring that marks the boundary between the known and the unknown. That boundary is always closer than one thinks.

We agreed that quantum internet searches are a few years off. I had spent the afternoon in Jeff Kimble's lab at Caltech contemplating the first node of the the quantum internet — a single atom trapped in an optical cavity, capable of exchanging entangled photons with any other nodes, as soon as they are brought into existence. But when the quantum internet has only one node, containing one bit, Q-Google (Quoogle?) is not yet necessary. Sergey and Larry and I noted that when it is up and running, the quantum internet should offer all sorts of wacky possibilities for quantum internet search. Searches could be made significantly more efficient, for example, by using quantum parallelism to explore every node of the quantum internet simultaneously. Problems arise, however, from the fact that quantum bits can't be cloned. I cannot go further into our discussion as that would involve proprietary information concerning quantum internet protocols (e.g., Q-TCPIP).

Sergey broached the subject of massive entanglement and ...."

Very interesting stuff, thanks!

I think it's important to point out that he is "Professor of Quantum-Mechanical Engineering, MIT"

That is a REALLY BIG title. Holy crap.
