I've seen a few breakdowns over the years, short answer is yes, my statements here aren't based on anything I know, only what seems most plausible from actual smart people bitching. The number of qbits required to crack sha 256 would dwarf the number of atoms in the universe, so its a non starter. For that matter, the number of qbits required to do any amount of meaningful work is beyond the pale of what we are putting on a chip. Worse yet is how much deception there is in this industry, a lot of things are being called quantum computing when they aren't even close. Finally, satoshi themself I believe said due to the nature of quantum computing it would require the reuse of public keys (which is disabled by default on modern wallets) to leak enough information to crack the private key.

There certainly is a good amount of disinformation on quantum computing out there, but Google's recent published works make no mistake that real strides are being made. It's good that there's flexibility in the system and people actively planning for it.
It is good no one is taking the threat sitting down. Google though is making a lot of errors here, they seem to be comparing the work load of a supercomputer to a quantum computer factoring prime numbers. That super computer would not hash bitcoin blocks as fast as a relatively tiny amount of asics, for instance, if they compared this quantum computer to silicon that's designed for prime factorization then this might be more meaningful.
