Algebraic quantum structures for reference frame-independent quantum teleportation and pseudo-telepathy

Abstract:

Part I: We present two new schemes for teleportation of a quantum state between parties whose local reference frames are misaligned by the action of a compact Lie group G. These schemes require no prior alignment of reference frames and are unaffected by arbitrary changes in reference frame alignment during execution, suiting them to situations of rapid reference frame drift. Our tight scheme yields improved purity compared to standard teleportation, in some cases substantially ---includin...
