A link between symmetries of critical states and the structure of SLOCC classes in multipartite systems
Oskar Słowik, Martin Hebenstreit, Barbara Kraus +1
Central in entanglement theory is the characterization of local transformations among pure multipartite states. As a first step towards such a characterization, one needs to identi…
Measurement outcomes that do not occur and their role in entanglement transformations
Martin Hebenstreit, Matthias Englbrecht, Cornelia Spee +2
The characterization of transformations among entangled pure states via local operations assisted by classical communication (LOCC) is a crucial problem in quantum information theo…
Matrix Product States: Entanglement, symmetries, and state transformations
David Sauerwein, Andras Molnar, J. Ignacio Cirac +1
We analyze entanglement in the family of translationally-invariant matrix product states (MPS). We give a criterion to determine when two states can be transformed into each other…
