Abstract
We propose a quantum secure direct communication protocol using SU (2)- invariant separable states, identified as separable equivalents of two-qubit entangled Werner states in [Bharath & Ravishankar, Phys. Rev. A 89, 062110}]. These states can be experimentally realized as incoherent superpositions of separable polarisation-OAM states.
