Seven selected papers by mathematicians, physicists, and computer scientists report research results with an emphasis on quantum communication. Among their topics are Cartan decomposition and entangling power of braiding quantum gates, an efficient algorithm for a quantum analogue of 2-SAT, quantum computational curvature and the Jacobi fields, and space and time lattices in frame fields of quantum representation of real and complex numbers.
