Title: Mutually Unbiased Bases Revisited
Abstract: First Hermann Weyl, then Julian Schwinger laid the foundations for a systematic classification of quantum degrees of freedom and paved the way toward a technical formulation of Bohr's Principle of Complementarity, on which all of quantum kinematics is based. Central to the issue are complementary observables and their mutually unbiased bases (MUB), which have attracted much interest in recent years. MUB are very useful for many quantum-information purposes. There are seemingly simple, but actually very difficult, problems about MUB that have not been solved despite the efforts of many. I will review the subject and report recent developments.
