Are mixed states really the main battlefield? It seems to me that the subjective vs. objective debate for mixed states is not much different from the classical case, except it’s much messier mathematically, just as Eliezer writes.
Rather, the interesting question for me (and, as I understand, the quantum Bayesian crowd) is whether pure quantum states should also be interpreted as states of knowledge.
