Query: Proceedings of the 15th International Conference on Quantum Physics and
  Logic   Quantum Physics and Logic is an annual conference that brings together
researchers working on mathematical foundations of quantum physics, quantum
computing, and related areas, with a focus on structural perspectives and the
use of logical tools, ordered algebraic and category-theoretic structures,
formal languages, semantical methods, and other computer science techniques
applied to the study of physical behaviour in general. Work that applies
structures and methods inspired by quantum theory to other fields (including
computer science) is also welcome.
