Multipartite Entanglement Analysis From Random Correlations
Lukas Knips, Jan Dziewior, Waldemar Kłobus +5
Quantum entanglement is usually revealed via a well aligned, carefully chosen set of measurements. Yet, under a number of experimental conditions, for example in communication with…
Measurement-Disturbance Tradeoff Outperforming Optimal Cloning
Lukas Knips, Jan Dziewior, Anna-Lena K. Hashagen +3
One of the characteristic features of quantum mechanics is that every measurement that extracts information about a general quantum system necessarily causes an unavoidable disturb…
Universality of local weak interactions and its application for interferometric alignment
Jan Dziewior, Lukas Knips, Demitry Farfurnik +7
The modification of the effect of interactions of a particle as a function of its pre- and postselected states is analyzed theoretically and experimentally. The universality proper…
String Quantization and the Shuffle Hopf Algebra
Dorothea Bahns, Jasmin D. A. Meinecke
The Poisson algebra of invariants of the Nambu-Goto string, which was first introduced by K. Pohlmeyer in 1982, is described using the Shuffle Hopf algebra. In partic…
