Lay summary

The purpose of this program is to fund extended research visits of distinguished scientists from around the world to the Basel center for quantum computing and quantum coherence (QC2). The topics of research will center around the quantum physics of condensed matter with special focus on quantum information science. The program hosts both theoretical and experimental researchers. Currently, there are six research groups from the Department of Physics in Basel participating in the program, the group leaders are: Proff. Bruder, Loss, Poggio, Schoenenberger, Treutlein, and Zumbuehl. The ongoing research includes: quantum control, quantum measurements, and foundations of quantum mechanics, quantum coherence in hybrid systems, spin decoherence and nuclear magnetism in low-dimensional interacting systems, spintronics and superconductivity in nanowires and carbon nanotubes, exotic quantum states (Majoranas, fractionally charged fermions, etc.), quantum entanglement, quantum optics and BEC, etc.

Abstract

The Basel QC2 Center (http://qc2.unibas.ch) was established in 2005 from research groups in both theoretical and experimental condensed matter physics at the University of Basel. The QC2 Center devotes its research to quantum information science with particular focus on its physical aspects such as implementations of quantum computers in solid state systems. This requires the study of a wide range of quantum effects in many-body systems displaying quantum coherence and entanglement, in and out of equilibrium. A particular focus is the study of semi-conducting (spin qubit) and superconducting nanostructures, and various hybrid systems involving light-matter interaction and Bose-Einstein condensates. The field of quantum computing also brings together very abstract ideas from information science and complexity theory to the theory of quantum dynamics in systems coupled to a variety of environments. This visitor program is intended to attract the key scientists in this multidisciplinary field for extended visits to Basel with the particular goal of initiating and exploring new developments in quantum computing and quantum coherence.
