Deciding Observability in Quantum Dynamics Made Easy — •Thomas Schulte-Herbrüggen and Markus Wiener — Technical University of Munich (TUM)

In quantum engineering a fundamental question arises: given a controlled quantum dynamical system, for which observables can measurements give full information for system identification?

In finite-dimensional closed systems, a unified (Lie) frame of quantum systems theory settles this observability problem—as will be illustrated in paradigmatic n-qubit systems. Implications and generalisations will be outlined as well.

Keywords: system identification; quantum control
