Why does it need to be in physics? What would that look like, a Qualia Boson? It could be an emergent property like life itself. Physics doesn't "explain" life, it explains the physical mechanisms behind the chemical interactions that ultimately produce life by virtue of self-replicating patterns spreading and mutating. There is no Life is physics, and yet we see it all around it because it emerges as a complex result of fundamental rules. My expectation is that experience is emergent from computation that controls an agent and models the world around that agent, and that experience isn't a binary. A tree is more aware than a rock, an ant more than a tree, a squirrel more than an ant, and so on until you reach humans, but there may not be any real change in kind as the conditions for experience become more developed. I guess my real point is that I don't view experience or consciousness as something special or exceptional. My guess is that over time we come to understand how the brain works better and better but never find anything that definitively explains consciousness because it's totally subjective and immeasurable. We eventually produce computers complex enough to behave totally convincingly human, and they will claim to be conscious, maybe even be granted personhood, but we'll never actually know for sure if they experience the world, just like we don't know that other humans do.
