Quantum communication using a bounded-size quantum reference frame

Stephen D Bartlett, Terry Rudolph, Robert W Spekkens, Peter S Turner
2009 New Journal of Physics  
We assume that the token is prepared in a special state that has particularly nice group-theoretic properties and that is near-optimal for transmitting information about the sender's frame.  ...  Indeed, if the receiver only possesses a bounded-size quantum token of the sender's reference frame, then the decoding is imperfect, and we can describe this effect as a noisy quantum channel.  ...  Boileau, Matthias Christandl and Renato Renner for helpful discussions.
