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…
Simulating extremal temporal correlations
Cornelia Spee, Costantino Budroni, Otfried Gühne
The correlations arising from sequential measurements on a single quantum system form a polytope. This is defined by the arrow-of-time (AoT) constraints, meaning that future choice…
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…
Certifying the purity of quantum states with temporal correlations
Cornelia Spee
Correlations obtained from sequences of measurements have been employed to distinguish among different physical theories or to witness the dimension of a system. In this work we sh…
Characterizing multipartite entanglement classes via higher-dimensional embeddings
Christina Ritz, Cornelia Spee, Otfried Gühne
Witness operators are a central tool to detect entanglement or to distinguish among the different entanglement classes of multiparticle systems, which can be defined using stochast…
