Relativistic entanglement of two massive particles
Nicolai Friis, Reinhold A. Bertlmann, Marcus Huber +1
We describe the spin and momentum degrees of freedom of a system of two massive spin-- particles as a 4 qubit system. Then we explicitly show how the entanglement cha…
Detection of high-dimensional genuine multi-partite entanglement of mixed states
Marcus Huber, Florian Mintert, Andreas Gabriel +1
We derive a general framework to identify genuinely multipartite entangled mixed quantum states in arbitrary-dimensional systems and show in exemplary cases that the constructed cr…
Mixed State Entanglement Measures for Intermediate Separability
Tsubasa Ichikawa, Marcus Huber, Philipp Krammer +1
To determine whether a given multipartite quantum state is separable with respect to some partition we construct a family of entanglement measures R_m. This is done utilizing gener…
A geometric comparison of entanglement and quantum nonlocality in discrete systems
Christoph Spengler, Marcus Huber, Beatrix C. Hiesmayr
We compare entanglement with quantum nonlocality employing a geometric structure of the state space of bipartite qudits. Central object is a regular simplex spanned by generalized…
Two distinct classes of bound entanglement: PPT-bound and `multi-particle'-bound
B. C. Hiesmayr, M. Huber
We introduce systematically with the help of Weyl operators novel classes of multipartite and multidimensional states which are all bound entangled for arbitrary dimension. We find…
Two computable sets of multipartite entanglement measures
Beatrix C. Hiesmayr, Marcus Huber, Philipp Krammer
We present two sets of computable entanglement measures for multipartite systems where each subsystem can have different degrees of freedom (so-called qudits). One set, called 'sep…
