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…
Genuine temporal correlations can certify the quantum dimension
Cornelia Spee, Hendrik Siebeneich, Timm Florian Gloger +5
Temporal correlations in quantum mechanics are the origin of several non-classical phenomena, but they depend on the dimension of the underlying quantum system. This allows one to…
Certifying quantum memories with coherence
Timo Simnacher, Nikolai Wyderka, Cornelia Spee +2
Quantum memories are an important building block for quantum information processing. Ideally, these memories preserve the quantum properties of the input. We present general criter…
