If you have a question about this talk, please contact Neel Krishnaswami. Loosely speaking, a pair of quantum observables is called “complementary” when knowledge of one implies ignorance of the other. Complementarity is responsible for much of the “weirdness” in quantum theory. The classic example is position and momentum, however finite dimensional examples such as the Z and X spins are used throughout quantum information processing. Thanks to a theorem of Coecke, Pavlovic and Vicary, quantum observables can be identified with certain Frobenius algebras; from this perspective complementary observables are those whose algebras satisfy some additional equations.
