14 September 2021, Baden-Wuerttemberg, Stuttgart: In a laboratory of the company Q.ANT, engineers Kirill Spasibko (r) and Louise Hoppe (l) prepare the test of a newly developed photonic chip with a laser beam. The Trumpf subsidiary Q.ANT has developed what it claims is a unique process that will enable the mass production of quantum computer chips in the future. The special feature is that the process also allows ordinary mainframe computers to be expanded to include processors that work with quantum technology, bringing the use of quantum computers closer.
