Well, luckily the information we are sending is not millions of bits. I 
do not know how many photons you need to actually encode a logical bit 
but I guess we are not in the millions. Also, are there actual 
implementations that implement QKD and use a single photon to encode a 
single state? Even then, you are comparing apples and oranges as you are 
talking about the full communication in the one case and a single state 
in the other (QKD also needs a classical channel, requires far more than 
one state, etc.pp.) [sorry for the nitpicking]

Cheers,

Andy
