On the entanglement structure in quantum cloning
D. Bruss, C. Macchiavello
We study the entanglement properties of the output state of a universal cloning machine. We analyse in particular bipartite and tripartite entanglement of the clones, and discuss t…
Entanglement properties of composite quantum systems
K. Eckert, O. Gühne, F. Hulpke +6
We present here an overview of our work concerning entanglement properties of composite quantum systems. The characterization of entanglement, i.e. the possibility to assert if a g…
Experimental detection of entanglement via witness operators and local measurements
O. Guehne, P. Hyllus, D. Bruss +4
In this paper we address the problem of detection of entanglement using only few local measurements when some knowledge about the state is given. The idea is based on an optimized…
Quantum computing in optical microtraps based on the motional states of neutral atoms
K. Eckert, J. Mompart, X. X. Yi +4
We investigate quantum computation with neutral atoms in optical microtraps where the qubit is implemented in the motional states of the atoms, i.e., in the two lowest vibrational…
Detection of entanglement with few local measurements
O. Guehne, P. Hyllus, D. Bruss +4
We introduce a general method for the experimental detection of entanglement by performing only few local measurements, assuming some prior knowledge of the density matrix. The ide…
Quantum Correlations in Systems of Indistinguishable Particles
K. Eckert, J. Schliemann, D. Bruss +1
We discuss quantum correlations in systems of indistinguishable particles in relation to entanglement in composite quantum systems consisting of well separated subsystems. Our stud…
