Phase I / 2011 - 2014

A key goal of this NCCR is to facilitate strong interactions between the involved groups and to overcome the boundaries between different approaches to achieve unprecedented levels of quantum control and manipulation.

The following shows the different approaches (A and B, respectively) and the topical sections (1 to 3) according to which the research network was organized.

Solid state systems -
B:
Quantum Spintronics
B1: Si, Ge, and GaAs systems
B2: Carbon-based materials

Section 2

Entanglement and strong correlation in few and many quantum systems

Bell-state measurements; realization of new quantum states formed by strong correlation
