Did you read about Google's partnership with NASA and UCSD to build a quantum computer of 1000 qubits?

Technologically exciting, but ... imagine a world without encryption. As if all locks and keys on all houses, cars, banks, nuclear vaults, whatever, disappeared, only incomparably more consequential.

That would be catastrophic, for business, economies, governments, individuals, every form of commerce, military communication....

Didn't answer your question, I am sorry, but as a "fan" of quantum computing, and also a person with a long time interest in the quantum zeno effect, free will, and the implications for consciousness (as often discussed by Henry Stapp, among others), I am both excited, yet feel a certain trepidation. Like I do about nanotech.

I am writing a long essay and preparing a video on the topic, but it is a long way from completion. I do think it (qc) will have a dramatic effect on artifactual consciousness platforms, and I am even more certain that it will accellerate superintelligence (which is not at all the same thing, as intelligence and consciousness, in my opinion, are not coextensive.)
