Multipartite entanglement in quantum spin chains
D. Bruss, N. Datta, A. Ekert +2
We study the occurrence of multipartite entanglement in spin chains. We show that certain genuine multipartite entangled states, namely W states, can be obtained as ground states o…
A two-way algorithm for the entanglement problem
Florian Hulpke, Dagmar Bruss
We propose an algorithm which proves a given bipartite quantum state to be separable in a finite number of steps. Our approach is based on the search for a decomposition via a coun…
Distributed quantum dense coding
Dagmar Bruss, Giacomo Mauro D'Ariano, Maciej Lewenstein +3
We introduce the notion of distributed quantum dense coding, i.e. the generalization of quantum dense coding to more than one sender and more than one receiver. We show that global…
Generation and detection of bound entanglement
Philipp Hyllus, Carolina Moura Alves, Dagmar Bruss +1
We propose a method for the experimental generation of two different families of bound entangled states of three qubits. Our method is based on the explicit construction of a quant…
Simplifying Schmidt number witnesses via higher-dimensional embeddings
Florian Hulpke, Dagmar Bruss, Maciej Lewenstein +1
We apply the generalised concept of witness operators to arbitrary convex sets, and review the criteria for the optimisation of these general witnesses. We then define an embedding…
