Was this a quantum computer? Is Bitcoin's security at risk? WTFFFF seriously somebody explain this NOW

can't wait, supercomputes in every city will make LINK obsolete

So the PC found a loyal woman?

Cannot see the paper so I dunno but so far quantum supremacy demonstrations all concern very specific, contrived (and probably useless) problems.
Maybe they implemented Shor's algo but would be very surprising.
Also D-wave has had a suspicious approach to quantum comp, it's not proven at all that they can actually do quantum computing with their system, they're not above making false claims.
Even if they did, your wallet is fine because the address is not a legible public key but a hash of it and QC most probably cannot reverse these types of hash functions

What if the cpu just got lucky and pi ked the right answer? But anyways why don't we jjst implement a pw attempt limit?

Can quantum encryption avoid this potential catastrophe?
