Focus is on two parties with Hilbert spaces of dimension d, i.e. “qudits”. In the state space of these two possibly entangled qudits an analogue to the well known tetrahedron with the four qubit Bell… (More)

We investigate the state space of bipartite qutrits. For states which are locally maximally mixed we obtain an analog of the “magic” tetrahedron for bipartite qubits—a magic simplex W. This is… (More)

Investigation at a φ–factory can shed light on several debated issues in particle physics. We discuss: i) recent theoretical development and experimental progress in kaon physics relevant for the… (More)

We demonstrate genuine multipartite quantum entanglement of four photons in their orbital angular momentum degrees of freedom, where a high-dimensional discrete Hilbert space is attached to each… (More)

We consider an open quantum system which contains unstable states. The time evolution of the system can be described by an effective non-hermitian Hamiltonian Heff , in accord with the… (More)

Relevant aspects for testing Bell inequalities with entangled meson–antimeson systems are analyzed. In particular, we argue that the results of A. Go, J. Mod. Optics 51, 991 (2004), which nicely… (More)

For the entangled neutral kaon system we formulate a Bell inequality sensitive to CP violation in mixing. Via this Bell inequality we obtain a bound on the leptonic CP asymmetry which is violated by… (More)

First a generalized Bell-inequality for different times and for different quasispin states is developed. We focus on special quasi-spin eigenstates and times. The inequality based on a local… (More)

The quantitative formulation of Bohr’s complementarity proposed by Greenberger and Yasin is applied to some physical situations for which analytical expressions are available. This includes a variety… (More)
