"Dik Bouwmeester and his collegues at Oxford University will report in a
future issue of Science that they have now copied a photon's quantum state
with 81 per cent accuracy, coming within a hair's breadth of the theoretical
limit of 83 per cent."

New Scientist, 20020406, p23.

Maybe with a randomized bitstream, 83 per cent won't be enough.
