I'm always stuck on that little step where Alice tells Bob what basis
she used for each photon sent. Tells him how? They need integrity
protection and endpoint authentication for N bits of basis. Is the
quantum trick converting those N bits to N/2 privacy-protected bits
really as exciting as it's made out to be?
