I’ve actually built a working quantum encrypted link and spent considerable time studying the D-wave technology.

Very, very interesting. Then I'd like to ask a question, if you don't mind: Do you think there's any way the 'spooky action at a distance'/non-locality/EPR phenomenon can be used to actually communicate instantaneously? ie, open and close switches instantaneously, transfer 1's and 0's (computer language) instantaneously? Some other way?

No instantaneously conveyed information is possible; that's in the math. It really works exactly like the math says.

I can send you a packet of quantum entangled stuff which you can use as a one time pad to do perfect encryption or decryption. There is rather less market for that than you might think. And the hard part of quantum links is the part that goes "emit a single photon".

But for you people concerned about security look at the publicly available D-wave stuff which I believe is at 128 bits and double the bit-count for what NSA has. You really need >1024 bits for keys you really want to be secure for the foreseeable future.
