Confident entanglement detection via separable numerical range
Timo Simnacher, Jakub Czartowski, Konrad Szymański +1
We investigate the joint (separable) numerical range of multiple measurements, i.e., the regions of expectation values accessible with (separable) quantum states for given observab…
A complete hierarchy for the pure state marginal problem in quantum mechanics
Xiao-Dong Yu, Timo Simnacher, Nikolai Wyderka +2
Clarifying the relation between the whole and its parts is crucial for many problems in science. In quantum mechanics, this question manifests itself in the quantum marginal proble…
Entanglement detection with scrambled data
Timo Simnacher, Nikolai Wyderka, René Schwonnek +1
In the usual entanglement detection scenario the possible measurements and the corresponding data are assumed to be fully characterized. We consider the situation where the measure…
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…
