Title: Graph theory and Scrambling of Quantum Information. Uzy Smilansky
Abstract: The introduction of quantum computing brought with it the need to adopt classical and well - founded concepts from Information theory to the Quantum Mechanical world. In particular, concepts like Information Scrambling, Chaos and its measure in terms of Lyapunov exponents had to be reformulated to coexist with tenets of Quantum theory such as Heisenberg's uncertainty principle, while complying with Bohr's correspondence principle. I will try to show how a new approach based on concepts and results from Graph Theory offers a solution to the above mentioned difficulties. This talk is based on a joint work with Sven Gnutzmann.
