The article: > Fully useful quantum computers have the potential to reach computation speeds that are orders of magnitude faster than today’s supercomputers. It's not talking about the present, where IIUC quantum computers are basically useless for anything but research, not performing as well as classical computers because of noise and shortage of qubits.
