Abstract
We propose a protocol for remote transfers of information using SU (2)-invariant 2 × N separable states, identified as separable equivalents of the two-qubit entangled Werner states in [Bharath & Ravishankar, Phys. Rev. A 89, 062110]. They can be experimentally realised as incoherent superpositions of separable polarisation-OAM states.
