It's exciting and worrisome, getting onto the wrong hands, all at once.

If they push past quantum annealing into true quantum computing territory, the abilities will become terrifying. At that point, I think the project would be shut down, purchased by the US government, become highly regulated, and building and owning a quantum computer would be made illegal. It would be regulated like a new weapon of mass destruction and there would be alliances and treaties put in place. A true quantum computer could effortlessly break the encryption which is the backbone of our communication and financial system.

Scary stuff m8.

Check this article out which pretty much sums up what you stated and than some.

A true quantum computer could effortlessly break the encryption which is the backbone of our communication and financial system.

Not if the financial systems etc were also upgraded to quantum encryption. Same as how current computer systems would effortlessly break any 'code' that was deemed secure decades ago.

Not the "same".  Encryption which becomes less secure over the years is largely just made more complex and run through a greater number of iterations to be made secure again.  Our encryption uses math, and to adjust the level of security, we control the complexity of the math in relation to the computational power available.  Shor's algorithm breaks the math problem so that the complexity of the math is irrelevant.  One is an iterative process, one is game-changing.  Shor's algorithm doesn't just run faster, Shor's algorithm breaks the math and converges on the solution effortlessly.

Do you think that every bank, every email account, every business (small and large), every server, every network, every computer, every phone, every app, EVERYTHING, will upgrade to quantum encryption in one day? No. That process would take years or decades. You can't simply say that the banks should upgrade to quantum encryption and then forget that everything that the banks communicate with would also need to support quantum encryption.

We don't know if it is even possible to create a true quantum computer; a requirement to run Shor's algorithm. Let's find that out first. But, IF it turns out to be possible, the research will suddenly shutdown and will be guarded and highly desirable, until the rest of our infrastructure catches up.

"until the rest of our infrastructure catches up" ..yes, that is my point, it WILL catch up - they will have to, or they will fail.

The one will not happen until the other.  Your response seemed to indicate that financial systems should upgrade to quantum encryption preemptively.  I don't think that will happen for the majority.  Therefore, what I said stands.

LOL.. how the heck could they upgrade to quantum encryption preemptively if it doesn't exist yet? lol... wow ok.
 

hardware dongles for security ... with a moving code that fit the encryption algorithem

I am glad that you agree.
