Quantum communication, reference frames and gauge theory
arXiv:quant-ph/0602079 · doi:10.1103/PhysRevA.73.042306
Abstract
We consider quantum communication in the case that the communicating parties not only do not share a reference frame but use imperfect quantum communication channels, in that each channel applies some fixed but unknown unitary rotation to each qubit. We discuss similarities and differences between reference frames within that quantum communication model and gauge fields in gauge theory. We generalize the concept of refbits and analyze various quantum communication protocols within the communication model.
pretty pointless, published nonetheless
