Measurement-based quantum computation and statistical mechanics
Prof. Dr. Wolfgang Dür, Institut für Theoretische Physik, Universität Innsbruck

In the last decade we have seen spectacular advances in the control and manipulation of quantum
systems, with the promise of various applications of such emerging quantum technologies. One of the
goals in quantum information processing is the realization of quantum computers, devices that allow one
to solve certain problems much faster than any classical computer could. In this talk I will focus on
measurement-based quantum computation (MQC), a new computational paradigm that offers both
conceptual and practical advantages as compared to a standard gate based approach. In MQC, a highly
entangled quantum state is manipulated solely by single-qubit measurements, where quantum
correlations and entanglement serve as a resource to perform a quantum algorithm. Thereby not only the
experimental requirements for the realization of a quantum computer are shifted, but also new insights
into the origin of the power of quantum computers can be gained, e.g. by analyzing the role of
entanglement in this computational model.
