We consider the distribution of secret keys, both in a bipartite and a multipartite (conference)
setting, via a quantum network and establish a framework to obtain bounds on the …

Suppose that several parties jointly possess a pure multipartite state,| ψ⟩. Using local
operations on their respective systems and classical communication (ie LOCC), it may be …

The transformations of W-type entangled states by using local operations assisted with
classical communication are investigated. For this purpose, a parametrization of the W-type …

Understanding multipartite entanglement is a key goal in quantum information.
Entanglement in pure states can be characterized by considering transformations under …

A necessary and sufficient condition of the possibility of a deterministic local operations and
classical communication (LOCC) transformation of three-qubit pure states is given. The …

In this article, we extend recent results concerning random-pair Einstein-Podolsky-Rosen
distillation and the operational gap between separable operations (SEPs) and local …

In this article we obtain results for the task of converting a single N-qubit W-class state (of the
form x 0| 00... 0〉+ x 1| 10... 0〉+⋯+ x N| 00... 1〉) into maximum entanglement shared …

The following submission constitutes a guide and an introduction to a collection of articles
submitted as a Ph. D. dissertation at the University of Gda\'nsk. In the dissertation, we study …

It is well known that quantum states that can be transformed into each other by local unitary
transformations are equal from the information theoretic point of view. This defines …

Most applications in quantum information processing make either explicit or implicit use of
entanglement. It is thus important to have a good understanding of entanglement and the …
