Theory of everything must include consciousness. In this article, we focus on introducing the subjective experience (SE) aspect of consciousness in modern quantum physics, namely, loop quantum gravity (LQG) and string theory by using the methodology of examining invariance of these theories under the PE‐SE transformations, where PEs (proto‐experiences) are precursors of SEs. In our dual‐ aspect‐dual‐mode PE‐SE framework, (i) each of strings, loops, elementary particles, inert matter, or neural‐networks has physical (material) and mental aspects, and (ii) there are three competing hypotheses: superposition based H1, superposition‐then‐ integration H2, and integration based H3 as discussed in Part I. In Part I and Part II of this series of 3 articles, we introduced the SE aspect of consciousness in classical and orthodox quantum physics, respectively, which are invariant under PE‐SE transformations. In the current Part III, the critical components of LQG with Palatini action appear invariant under this transformation. In string theory, for H1 and H2, we quantitatively introduce the superposition of potential experiences (SEs/PEs) in the mental aspect of bosonic and fermionic strings using the Polyakov action
