A Moment for Random Measurements
Lukas Knips
Quantum entanglement is one of the core features of quantum theory. While it is typically revealed by measurements along carefully chosen directions, here we review different metho…
Gaussian state entanglement witnessing through lossy compression
Waldemar Klobus, Pawel Cieslinski, Lukas Knips +2
We propose a method to witness entanglement between two continuous-variable systems in a Gaussian state. Its key ingredient is a local lossy state transfer from the original spatia…
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…
Measurements of nonlocal variables and demonstration of the failure of the product rule for a pre- and postselected pair of photons
Xiao-Ye Xu, Wei-Wei Pan, Qin-Qin Wang +9
We report the first implementation of the von Neumann instantaneous measurements of nonlocal variables which becomes possible due to technological achievements in creating hyperent…
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…
