  Motivated by string theory and standard model physics, we discuss the
possibility of other particles-based quantum information. A special attention
is put on the consideration of the graviton in light of the gravitational wave
detection. This may offer a new take in approaching quantum information using
messenger particles. The construction is readily extended to higher dimensional
qubits where we speculate on possible connections with open and closed string
sectors in terms of quiver and graph theories, respectively. In particular, we
reveal that the vectorial qubits could be associated with skeleton diagrams
considered as extended quivers.
