On the 4th of September, the new Christian Doppler Laboratory for optical quantum computers has opened at the University of Vienna! Under the direction of Philip Walther, researchers are developing new technologies for quantum computers based on photonic platforms. These quantum computers are to be used in a versatile way and for practical applications. By providing a photonic quantum computer in the cloud, scientists and the general public will be able to work with quantum algorithms. Christian Doppler Laboratories are jointly financed by the public sector and the participating companies. The most important public funding body is the Federal Ministry for Digitalization and Business Location (BMDW).
