We developed a quantum computer - demonstrator that can also work with laser light and that provides a universal set of quantum gates. It performs the operations of the gates with single photons or with coherent laser light. The quantum computer - demonstrator can be programmed by an electrooptical piezo based energy efficient polarizer POLARITE III, that is controlled by a Raspberry Pi 5. With it Qubits und optical quantum gates are controlled. Moreover, the quantum computer - demonstrator can illustrate the process of quantum teleportation, the transfer of a state of a qubit C to a qubit B via an entangled qubit A. This process represents a safe transfer of quantum information.
