    Yes category theory is used in quantum physics including the latest effort in post string theory.

    Here's a link to John Baez's explanation of how category theory relates to basic quantum mechanics. http://www.math.ucr.edu/home/baez/categories.html

    Take for example the quantization problem of Drinfel'd and Hopf structures. They are developed in a formal categorical sense.
