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…
Symmetries between measurements in quantum mechanics
H. Chau Nguyen, Sébastien Designolle, Mohamed Barakat +1
Symmetries are a key concept to connect mathematical elegance with physical insight. We consider measurement assemblages in quantum mechanics and show how their symmetry can be des…
Quaternionic quantum theory admits universal dynamics only for two-level systems
Jonathan Steinberg, H. Chau Nguyen, Matthias Kleinmann
We revisit the formulation of quantum mechanics over the quaternions and investigate the dynamical structure within this framework. Similar to standard complex quantum mechanics, t…
Some quantum measurements with three outcomes can reveal nonclassicality where all two-outcome measurements fail to do so
H. Chau Nguyen, Otfried Gühne
Measurements serve as the intermediate communication layer between the quantum world and our classical perception. So, the question which measurements efficiently extract informati…
Quantum steering of Bell-diagonal states with generalized measurements
H. Chau Nguyen, Otfried Gühne
The phenomenon of quantum steering in bipartite quantum systems can be reduced to the question whether or not the first party can perform measurements such that the conditional sta…
Entanglement dynamics of two mesoscopic objects with gravitational interaction
H. Chau Nguyen, Fabian Bernards
We analyse the entanglement dynamics of the two particles interacting through gravity in the recently proposed experiments aiming at testing quantum signatures for gravity [Phy. Re…
