Extendability and complete extendability of Gaussian states

2016 · arXiv (Cornell University)

Motivated by the notions of $k$-extendability and complete extendability of the state of a finite level quantum system as described by Doherty et al (Phys. Rev. A, 69:022308), we introduce parallel definitions in the context …

Conditions for local transformations between sets of quantum states

2022 · Physical Review A

We study the problem of transforming a set of pure bipartite states into another using deterministic LOCC (local operations and classical communication). Necessary conditions for the existence of such a transformation are obtained using LOCC …
