Query: Mixed State Holonomies   Sjoqvist, Pati, Ekert, Anandan, Ericsson, Oi and Vedral (Phys. Rev. Lett. 85,
2845 [2000]) have recently "provided a physical prescription based on
interferometry for introducing the total phase of a mixed state undergoing
unitary evolution, which has been an elusive concept in the past". They note
that "Uhlmann was probably the first to address the issue of mixed state
holonomy, but as a purely mathematical problem". We investigate possible
relationships between these "experimental" and "mathematical" approaches, by
examining various quantum-theoretic scenarios. We find that the two
methodologies, in general, yield inequivalent outcomes.
