WebShort answer: A mixed state is a way of representing purely classical uncertainty within the same formalism as quantum uncertainty. Classical uncertainty is the kind we're used to … Web12. Now consider the following mixed state: ρˆ= 1 2π Z 2π 0 dφ α exp(iφ)ih α exp(iφ) . We can view this as a mixture of coherent states with random phase and ﬁxed amplitude α . We can perform the integration over φ, if we ﬁrst expand the coherent states in number states. The result is that we can rewrite the same mixed state as Web23 nov. 2015 · We investigate the spectral statistics of the difference of two density matrices, each of which is independently obtained by partially tracing a random bipartite pure quantum state.
