## Description

Qubit is a minimalist post-quantum messenger. Unlike most messengers, Qubit uses only symmetric cryptography — no RSA, no Diffie-Hellman, no elliptic curves. None of the schemes that quantum computers threaten.

How it works:
• Meet your contact in person. Agree on a shared key.
• Enter that key on both phones once. It never leaves the device.
• Every message is encrypted with AES-256-GCM on your iPhone before it leaves. The server only stores ciphertext.

What we don't do:
• No phone number, email, or address book required.
• No group chats, no attachments, no reactions. By design.
Open the channel only with someone you've actually met. That's the entire trust model. Simple. Auditable. Future-proof.
