Factorization with Gauss Sums — •Sabine Wölk and Wolfgang Schleich — Institut für Quantenphysik, Universität Ulm, D-89069 Ulm, Germany

Gauss sums manifest themeselves in many different physical phenomena. Therefore, the theoretical suggestion to factorize numbers with the help of the truncated Gauss sum led to many different realizations, such as the factorization with NMR, cold atoms, BEC, ultrashort laserpulses and classical light interferometry.

In the meantime, many questions such as "What happens, if we use rational numbers instead of integers as arguments of the truncated Gauss sum?" or "Is it possible to calculate Gauss sums efficient with the help of entanglement" turned up. In our talk, we will give a short overview of the topic of factorization with Gauss sums and try to answer sum of theses questions.
