Recently, a bundle theoretic description of massive single-particle statespaces, which is better suited for Relativistic Quantum Information Theory thanthe ordinary Hilbert space description, has been suggested. However, themathematical framework presented in that work does not apply to masslessparticles. It is because, unlike massive particles, massless particles cannotassume the zero momentum state and hence the mass shell associated withmassless particles has non-trivial cohomology. To overcome this difficulty,this paper suggests a new framework that can be applied to massless particles.Applications to the cases of massless particles with spin-1 and 2, namelyphoton and graviton, will reveal that the field equations, the gaugeconditions, and the gauge freedoms of Electromagnetism and General Relativitynaturally arise as manifestations of an inertial observer's perception of theinternal quantum states of a photon and a graviton, respectively. Finally, weshow that gauge freedom is exhibited by all massless particles, except thosewith spin-0 and 1/2.
