About how far does this leave us from a usable quantum processor? How far from all current cryptographic algorithms being junk?

Maybe they can use the same techniques for keeping their product management and feature roadmap for more than an hour.

Just in time for the fall of American democracy. What could possibly go wrong.

Seeing quantum computers work will be like seeing mathemagics at work, doing it all behind the scenes. Physically (for the small ones) it looks the same, but abstractly it can perform all kinds of deep mathematics.

108 qubits, but error correction duty for some of them?

What size RSA key can it factor "instantly"?
