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…
-uniform mixed states
Waldemar Klobus, Adam Burchardt, Adrian Kolodziejski +4
We investigate the maximum purity that can be achieved by k-uniform mixed states of N parties. Such N-party states have the property that all their k-party reduced states are maxim…
Higher dimensional entanglement without correlations
Waldemar Klobus, Wieslaw Laskowski, Tomasz Paterek +2
It has been demonstrated both theoretically and experimentally that genuine multipartite entanglement between qubits can exist even in the absence of multipartite correlations. Her…
Some exact results for the zero-bandwidth extended Hubbard model with intersite charge and magnetic interactions
Konrad Jerzy Kapcia, Waldemar Kłobus, Stanisław Robaszkiewicz
The extended Hubbard model in the zero-bandwidth limit is studied. The effective Hamiltonian consists of (i) on-site interaction and intersite (ii) density-density interaction…
