"Q-Day" gets thrown around a lot, usually as a vague, cinematic event — the day quantum computers arrive and crypto dies in a flash. That mental image is wrong, and the wrongness is dangerous, because it makes Q-Day feel like a single dramatic moment you'll

Most crypto projects introduce themselves with a problem. We'll get to ours — quantum computers, broken cryptography, the whole uncomfortable story — but not today. Today I just want to tell you what QP2 actually is, because the core idea is simple enough to explain over coffee, and once it
