Soo, 5000 qbits, ey? Then why are not those D-Wave already owning all the bitcoins in the world? I mean the biggest encryption used by wallets are protected by 4096 bit length, which is just a shy below 5000. Isn't quantum suppose to fly in microseconds at cracking public key encryption for that length?
I call this snake oil.

- danbruc 6y agoThe number of bits in an encryption key and the number of qubits in a quantum computer trying to break it are not related in general and even if they are related, the relation is not necessarily a linear relation. Also quantum computers do not in general offer an advantage when it comes to breaking encryption keys. They do, for example, for RSA because it relies on integer factorization and there is a faster quantum algorithm than a classical one, they do not - as far as we know - for AES for example.
