I did some reading of some who looked at the documentation that was posted before it was taken down.

The idea of quantum making the present encryption obsolete is not FUD. On that front the potential is real. However, from those who looked at the documents, they concluded that this version of quantum, if accurate, will not have that capability. That does not mean it will not be coming.

There are also teams of people who are working on developing quantum proof encryption. Ironically, one who has a vested interest is the NSA who has a whole lot more to lose than cryptocurrency people.

It is going to be interesting to see the tug-o-war that is going on.

There are many variables to quantum which makes it extremely difficult to develop a working product. Over the past few years, there were a lot of headlines about achieving quantum supremacy only to find out the reports were a bit exaggerated. Perhaps Google is onto something. However, if they are, I am sure they will be getting a visit from the Feds on that one. Keep in mind, not only is crypto at risk, but everything that is encrypted.

I am sure the U.S. Government is not exactly eager for the world to know all its secrets that could contradict the stories they put out to the mainstream.
