"Decoherence in quantum systems: Measurement and control"


Chengxing He , University of Virginia - Physics
[Host: Bob Jones]
ABSTRACT:

Quantum systems are fragile. Inhomogeneities in a sample’s environment can destroy its macroscopic coherence properties, while the coupling of components of a system to unmeasured/uncontrolled environmental degrees of freedom leads to microscopic decoherence. In this talk, I will discuss examples of my work related to macroscopic and microscopic coherence in cold atom ensembles, as well as possible approaches to preserving coherence. In addition, I will discuss a study of topological effects in atomic systems.
