10.5. Marcus Huber: Exploring Multipartite Entanglement
Exploring Multipartite Entanglement
Marcus Huber
Abstract:
Not only is multipartite entanglement a key feature of complex many-body
quantum systems, it also provides a fundamental resource in quantum
information processing.
Especially in complex and multidimensional systems full state
tomography, and thus complete information about the state of a system is
experimentally impossible to achieve. We therefore
require methods of detecting, classifying and quantifying multipartite
entanglement that scale favorably with the size of a system. We present
such a framework and show that
it can be utilized to explore the phenomenon of genuine multipartite
entanglement in various ways. We discuss the effect of noise and
experimental imperfection
in exemplary cases and show how this framework can be used to quantify
genuine multipartite entanglement.
