The MCQST Colloquium Series features interdisciplinary talks given by visiting international speakers. The monthly colloquial covers topics spanning all MCQST research units and will be broadcasted live, being made available to audiences worldwide. The main goal of the series is to create the framework for idea exchange, to strengthen links with QST leading groups worldwide, as well as to act as an integral part of the local educational environment.

MCQST Colloquium: Barbara Kraus

On November 9th, 2021, we are excited to invite you to attend the colloquium offered by Barbara Kraus from the University of Innsbruck.

Abstract

Quantum Information theory: From Entanglement to Quantum computing

I will talk about two important challenges within Quantum Information: Multipartite entanglement and the verification of quantum computations. The better understanding of multipartite entanglement is highly relevant for many areas of physics. The entanglement contained in states can be sorted (partially ordered) via the study of state transformations. However, it turns out that this partial order is trivial in the whole Hilbert space. As will be explained in the talk, this fact does not prevent us from a better understanding of entanglement properties which are relevant in a physical context. Entanglement plays also an important role in quantum computations and the verification thereof. I will discuss some very different protocols designed for the verification of quantum devices.
