Researchers all over the world have tried for more than 25 years to make a new type of computer that can solve much more complex problems than traditional computers are capable of. Professor Charles Marcus from the Niels Bohr Institute in Copenhagen is one of the leading researchers who have made major contributions to the development of quantum computers. He is interviewed about the state of the art of quantum computing by Science Journalist Jens Degett from Science Stories. The interview was made in connection with the first Quantum Computing Applications in Chemical and Biochemical Engineering Workshop organized by the Danish Technical University (DTU) Department of Chemical Engineering, Knowledge Hub Zealand and the American Institute of Chemical Engineers (AIChE) with more than 100 participants from around the world. The workshop was supported by the Novo Nordisk Foundation.
