Sort of a big philosophical question in quantum physics is what would be the experience of an entangled consciousness being (say, a human). However if you have to freeze the human to a complete metabolic halt (to achieve coherence), then it seems that it wouldn't be able to experience anything at all? And if you don't freeze the human, then it would be impossible to entangle it with an external system? Then, I guess one could argue that you could build a more thermally efficient system (say an AGI) that can experience and tell us about what it feels like to be entangled. But in order for it to experience/think, it would need to do some computation, so is subject to the Landauer's limit, and would need to release heat, which will also break the coherence? Has anyone done this kind of calculation?

Obviously whether we're entangled all the time varies depending on which model of QM you're working with (any linear model like MW would say we are), but I can't think of an interpretation that would predict a difference in subjective experience of a quantum system that's entangled from the POV of some observer outside the system.

Exactly > an interpretation that would predict a difference in subjective experience Chaos makes this effectively impossible to achieve, but: what if you (embedded in the experiment) could achieve the exact same end state via multiple different intermediate states, ie in one case you observed the qubit on, and in the other you observed it off. Now what would you remember?

    If you achieved the exact same end state, then by definition all of those paths would have the same subjective memory. The only way to achieve the exact same end state is if you actually didn't observe the qubit in two different states, or if you forgot about it. Your brain would be the same at the end.

      Agreed, it would have to be the same subjective memory, and you're right it's not a very interesting question. You'd probably have to either not observe it, or forget about it.
