Microelectronics For Quantum Technologies

The transition of the quantum mechanics realm into engineering applications is opening up a large number of disruptive quantum technological opportunities. Their success relies on the recent technological advancements, which enable the controlled creation of individual quantum mechanical systems as well as their direct manipulation and measurement. Quantum technological systems purposefully exploit principles of quantum mechanics that are not encountered in everyday experience. For example, a quantum system can exist in two or more different states simultaneously, with the indeterminacy only being removed by a measurement (superposition principle). In this way, quantum mechanics furthermore allows a strong non-local correlation (entanglement) of system components, which is quintessential for many applications.
