Query: Universal Property of Quantum Measurements of Equilibrium Fluctuations
  and Violation of Fluctuation-Dissipation Theorem   For macroscopic quantum systems, we study what are measured when equilibrium
fluctuations of macrovariables are measured in an ideal way that mimics
classical ideal measurements as closely as possible. We find that the
symmetrized time correlation (symTC) is always obtained for such measurements.
As an important consequence, we show that the fluctuation-dissipation theorem
(FDT) is partially violated as a relation between observed quantities in
macroscopic quantum systems even if measurements are made in such an ideal way.
