As experiments continue to push the quantum-classical
boundary using increasingly complex dynamical systems, the
interpretation of experimental data becomes more and more
challenging: when the observations are noisy, indirect, and
limited, how can we be sure that we are observing quantum
behavior? This tutorial highlights some of the difficulties
in such experimental tests of quantum mechanics, using optomechanics
as the central example, and discusses how the
issues can be resolved using techniques from statistics and
insights from quantum information theory.
