Wut. This is just false. D-Wave provides the "quantum computers" that others have and they're completely irrelevant when it comes to breaking ECC (or RSA, for that matter; ECC is broken by a variant of Shor's algorithm, which is used to break RSA). They're quantum annealing chips, not general-purpose quantum computers; they literally can't run Shor's algorithm, now or ever.
We're orders of magnitudes out (qubit-wise, on real quantum computers) from breaking RSA or ECC in practice, and the difficulty level is on the same order for both.
- duskwuff 6y agoI'm not convinced that D-Wave's hardware is relevant to anything beyond D-Wave's profits. It's neat that their technology works, I guess, but it isn't clear at this point that it does anything better than a classical computer could.
