As I edit my book for the 2nd edition, some of the updated charts/stats are v interesting!
This one is somewhat concerning.. (and if not, please enlighten me!)
When I wrote the first edition in early 2022, the qubit record was held by IBM and was only 127 qubits.
I just discovered that 18 months later, Oct 2023, a team in the Dept of Physics at TU Darmstadt broke the mark of 1,000 “individually controllable atomic qubits.”
While it has been estimated that a machine would need 13 million qubits to break SHA-256, it seems to me that at 10x every two years (which this team is aiming to do), it could take just ten years to get there.
Thoughts?
