-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…
Disproving hidden variable models with spin magnitude conservation
Pawel Kurzynski, Wieslaw Laskowski, Adrian Kolodziejski +3
The squares of the three components of the spin-s operators sum up to . However, a similar relation is rarely satisfied by the set of possible spin projections onto mutuall…
Unified approach to geometric and positive-map-based non-linear entanglement identifiers
Marcin Markiewicz, Adrian Kolodziejski, Zbigniew Puchala +3
Detecting quantumness of correlations (especially entanglement) is a very hard task even in the simplest case i.e. two-partite quantum systems. Here we provide an analysis whether…
Investigating nonclassicality of many qutrits by symmetric two-qubit operators
Marcin Markiewicz, Kamil Kostrzewa, Adrian Kolodziejski +2
We introduce a new method of investigating qutrit nonclassicality by translating qutrit operators to symmetric two-qubit operators. We show that this procedure partially resolves t…
Three-dimensional visualization of a qutrit
Pawel Kurzynski, Adrian Kolodziejski, Wieslaw Laskowski +1
We present a surprisingly simple three-dimensional Bloch sphere representation of a qutrit, i.e., a single three-level quantum system. We start with a symmetric state of a two-qubi…
Correlation-based entanglement criterion in bipartite multiboson systems
Wieslaw Laskowski, Marcin Markiewicz, Danny Rosseau +3
We describe a criterion for the detection of entanglement between two multi-boson systems. The criterion is based on calculating correlations of Gell-Mann matrices with a fixed bos…
