Rarely did experts agree so much: quantum technologies have what it takes to be a major "game changer". Among other things, they enable high-precision and high-performance sensor technology that is capable of recording brain waves more precisely, expanding the spectrum of microscopy or establishing physically secure communication links and new forms of encryption. Quantum computers are expected to easily solve problems that today's supercomputers fail at. This would make it possible to tackle demanding challenges in a wide variety of application fields, such as financial services, materials development, logistics and chemistry, in ways never before imagined.
