Quantum Information Processing in Non-Markovian Quantum Complex Systems

Exploring and exploiting the potential of quantum science for qualitatively new technologies - from quantum sensors and quantum electronics, over quantum computing and quantum telecommunications, to quantum photonics and quantum data mining - is among the most promising endeavors of fundamental research.

Yet, this agenda faces one central impediment: quantum phenomena are very well understood and controlled when manipulating individual, isolated quantum systems, while technological devices require the integration of a multitude of components, exhibit a significant level of complexity, and cannot be isolated from uncontrolled environments.

To tackle this challenge, the Freiburg-Nagoya consortium collects diverse international expertise from quantum information science, complex and open quantum systems, as well as mathematical physics, with the specific target to design quantum circuit models - paradigms of quantum computation - fit for technological integration.

Our team joins forces not only from Nagoya University and the University of Freiburg, but also from the University of Milan, the Abdus Salam International Centre for Theoretical Physics in Trieste (Italy), and Hanyang University (Korea). The aim is to initiate a strong research network which serves as a basis for collaborations on a global level, making Nagoya and Freiburg two main hubs for the study of quantum information theory in complex open quantum systems.
