WebFor a mixed state, let’s say for example a mixture of orthogonal states ψ 1 〉, ψ 2 〉, if we choose a basis including both states, the density matrix will be diagonal with just two entries w 1, w 2. Both these numbers must be less than unity, so ρ ^ 2 ≠ ρ ^. A mix of nonorthogonal states is left as an exercise for the reader.

Web1 for pure state < 1 for mixed state Tr ρ ⎧ = ⎨ ⎩ (9.13) The last expression reflects the fact that diagonal matrix elements can be 0 or 1 for pure states but lie between 0 and 1 for mixed states. In addition, when working with the density matrix it is convenient to make note of these trace properties: Webmixed state (10). Therefore, in order to ﬁnd the entropy for a mixed state (8), one may construct an associated virtual atom, then calculate its entropy, and, by virtue of the Araki–Lieb inequality, associate such atomic entropy with the ﬁeld mixed state. It is possible to use the Araki–Lieb inequality because

Any given system is identified with some finite- or infinite-dimensional Hilbert space. The pure states correspond to vectors of norm 1. Thus the set of all pure states corresponds to the unit sphere in the Hilbert space, because the unit sphere is defined as the set of all vectors with norm 1.
