Abstract
Quantum mechanics with a fundamental density matrix (W-QM) has been proposed and discussed recently. It motivates a new view called density matrix realism, according to which the ontic state of the universe is represented not by a wave function in quantum mechanics (QM), but by a density matrix in this theory, which may be a mixed state. In this paper, I argue that this view is inconsistent with the empirical equivalence between W-QM and QM.
