Is quantum computing relevant to symmetric encryption like OTP? GP was talking about asymmetric encryption. My limited understanding is that quantum computing is a threat to asymmetric encryption.
There's also the question of, if you can distribute a key which is at least the same size as your message over a secure channel - why not just distribute your message over that channel in the first place?
