>No one has actually really built such a quantum computer yet What are you talking about? We've had very small quantum universal computers for some time, and quantum annealers for two decades. How did you miss that? I regret to inform you that low bit strength RSA was even broken with a quantum annealer, not even a universal quantum machine. the NSA is a customer of D-Wave. IBM's quantum roadmap has them shipping 1121 qubit machine next year, this year they've shipped a 400+ qubit machine. So far they've been able to keep doubling the number of qubits every year. These are universal quantum computers. If they can keep scaling at that rate, both RSA and ECDSA are toast within a decade. |
