Saw a comment on a banking thread that said that Quantum Computing will kill crypto, I assume because it would be able to edit the blockchain and thus killing the entire point of bitcoin, but how exactly would it do this? How does it work and why does it mean all current encryption would become useless?

With 897 physical qubits (75 logical qubits) a dwave was able to factor 200099 in 3.5 seconds. They need 12x more physical because literally anything interacting with the bits ruins the computation (runs at 25 millikelvin, nearly absolute zero).
So using the same method to factor a 600 digit prime instead of a 6 digit prime sounds pretty far off.
And when it does happen, with some kind of breakthrough hardware design, they're not going to be stealing your $1k bitcoin wallet they're going to keep it secret as long as possible so they can use it on really important stuff.
