With all these buzz about quantum computer's threat to current encryption techniques, we could also use quantum computing against itself. I recently watched a good video, which is 15 minutes long, regarding these encryption techniques and how quantum computers can protect itself from other attackers.

And another thing to mention, quantum computer made by Google is nowhere near the needed qubits to break current encryption. I think Google's quantum computer is somewhere 50, while the needed to break is near 250.

Yes but you don't have a Quantum Computer. There is a time transition period, the first Quantum Computers will be very few and owned only by large governmental or private organizations, until technology advances to the point it could reach the masses (become Personal Quantum Computers). By then, i expect everyone would be using quantum crypto. But until then Quantum Computing will remain institutional, in the hands of few, just like classic computers were until the 70ies.

Bitcoin has proposal mitigations, its been kinda set aside "for now", but core developers should consider implementing those before it becomes obvious they are needed, or it would be too late by then.

Also, as i have tried to explain before, any such advancements made within the USA can be ordered silent. Since its still early they (may) have not acted, but a time will come when you hear no more news, then the likes of the NSA will have complete clear text like access to all encrypted communications, as if we were back in the early 90ies. Later, the other even more oppressive regimes will as well... Given the way things are in this world, most likely China will get it (from America) and keep quiet as well, except suddenly their State repression becomes more efficient there as well.

As i am guessing, Google and IBM are just probably fighting over State contracts, they both will probably be hired, and ordered to shut up (gag order) by National Security. That's the riskier period, and you won't see it coming, that's the whole point...
