Approximate and ensemble local entanglement transformations for multipartite states
David Gunn, Martin Hebenstreit, Cornelia Spee +2
Understanding multipartite entanglement is a key goal in quantum information. Entanglement in pure states can be characterised by considering transformations under Local Operations…
Identifying families of multipartite states with non-trivial local entanglement transformations
Nicky Kai Hong Li, Cornelia Spee, Martin Hebenstreit +2
The study of state transformations by spatially separated parties with local operations assisted by classical communication (LOCC) plays a crucial role in entanglement theory and i…
State transformations within entanglement classes containing permutation-symmetric states
Martin Hebenstreit, Cornelia Spee, Nicky Kai Hong Li +2
The study of state transformations under local operations and classical communication (LOCC) plays a crucial role in entanglement theory. While this has been long ago characterized…
Transformations in quantum networks via local operations assisted by finitely many rounds of classical communication
Cornelia Spee, Tristan Kraft
Recent advances have led towards first prototypes of quantum networks in which entanglement is distributed by sources producing bipartite entangled states. This raises the question…
Signaling between time steps does not allow for nonlocality beyond hidden nonlocality
Cornelia Spee
Hidden nonlocality is the phenomenon that entangled states can be local in the standard Bell scenario but display nonlocality after local filtering. However, there exist entangled…
Genuine Multipartite Entanglement in Time
Simon Milz, Cornelia Spee, Zhen-Peng Xu +3
While spatial quantum correlations have been studied in great detail, much less is known about the genuine quantum correlations that can be exhibited by temporal processes. Employi…
