The hype surrounding the quantum computer is fuelling the fantasy of a better world.

It is supposed to reduce logistics costs by making freight transport more efficient. It could also find solutions for the energy storage of renewable energies. And a Swiss start-up that produces artificial lungs wants to use quantum algorithms to conduct research even more efficiently in the future, cure cancer and make animal experiments obsolete. Today, a private investor is already enabling start-ups to use quantum computers commercially. But the technology is only at the beginning and the potentials and dangers of these supercomputers are close together...
