Quantum computers provide a potential for very fast computations [1, 2]. So, quantum computers are especially interesting for students at high schools, professional schools or at universities [3]. For such students, a demonstration experiment is very useful. Here, we present a demonstration experiment that is based on an interferometer and that provides a CNOT quantum gate. For it, we modified a similar experiment [4]. We present the demonstration experiment, experimental results and an extension to a universal set of quantum gates. Moreover, we show how quantum algorithms such as the Groover algorithm can be provided by such a universal set of quantum gates.
