Quantum computers: promise, problems and possible solutions
Prof. Dr. Dieter Suter (Technische Universität Dortmund)

The "Digital Revolution" that transformed our lives and our economy is based on the ubiquity of information-processing devices whose processing power increased exponentially, following Moore's law. As this trend is approaching fundamental physical limits, new directions are explored for even more powerful computational devices based on quantum mechanical systems. The main difficulty for the implementation of such devices is the fragility of information stored in coherent superpositions of quantum mechanical eigenstates. This talk will highlight some of the potential and difficulties of this approach and demonstrate possible solutions that may eventually lead to reliable quantum computers.
