24. Detection of typical bipartite quantum correlations by local generalized measurements

Gernot Alber (Technical University of Darmstadt)

Detection of genuine quantum correlations, such as entanglement or steerability, by local quantum measurements, which can possibly be performed by far distant observers, are of particular interest for applications in quantum key distribution and quantum communication.
In this context the natural question arises how does the effectiveness of detecting such genuine quantum correlations depend...

25. Nonlinear quantum dynamics and its potential applications in quantum information

Tamás Kiss (Wigner RCP)

Nonlinear evolution is not a usual phenomenon in quantum physics. It is possible to define a time-evolution for an ensemble of equally prepared systems in a somewhat unusual way: take N systems, apply an entangling unitary transformation, measure all but one of the systems and, depending on the measurement results, keep or throw away the remaining system. This procedure applied to the whole...

26. Symmetries in Quantum Information Science

Adrián Solymos (Wigner RCP)

Symmetries play a fundamental role in physics: from conservation laws and the unification of different theories to the simplification of complex problems to tractable ones. They are an indispensable tool and continue to be a driving force in research. This talk explores two topics from Quantum Information Science that places symmetry, and
therefore group theory, in the spotlight. First, the...
