You seem not to understand quantum computing. Dwaves 2k qbit is not a full computer its annealing so only good for.certain things. Google and ibm will have 100 qbit ones end of year. These are general purpose versions! Exciting for some.not so exciting for others. Assymetric encryption is vulnerable. Sha384 and above is safe for now but less is not. I know of an attack on bitcoin even with one way hashes of pubkeys to create base58 addresses but i wont scare the community. I will solve the issues though and am doing research on PQ algos that will be safe. A new elliptical curve is generally needed and one way hashing.
Btw 80 qbits can simulate an entire human body down to cell level.
I do understand the dangers of QC, I am just skeptical about the existence of any. It may very well be a scaremongering tactic or a marketing gimmick to sell some computers.
Until I dont see an actual one I will remain skeptical because this is an extraordinary tech and requires extraordinary evidence. Of course by then it will be too late, so I agree, post quantum cryptography is a priority.
9 qubit already exists.. goto the cloud and give it a try. Its easy to.scale once its done. Just a matter of time.
