Spin geometry of entangled qubits under bilocal decoherence modes
Katharina Durstberger
The Lindblad generators of the master equation define which kind of decoherence happens in an open quantum system. We are working with a two qubit system and choose the generators…
Decoherence modes of entangled qubits within neutron interferometry
Reinhold A. Bertlmann, Katharina Durstberger, Yuji Hasegawa
We study two different decoherence modes for entangled qubits by considering a Liouville - von Neumann master equation. Mode A is determined by projection operators onto the eigens…
Optimal Entanglement Witnesses for Qubits and Qutrits
Reinhold A. Bertlmann, Katharina Durstberger, Beatrix C. Hiesmayr +1
We study the connection between the Hilbert-Schmidt measure of entanglement (that is the minimal distance of an entangled state to the set of separable states) and entanglement wit…
Berry phase in entangled systems: a proposed experiment with single neutrons
Reinhold A. Bertlmann, Katharina Durstberger, Yuji Hasegawa +1
The influence of the geometric phase, in particular the Berry phase, on an entangled spin-1/2 system is studied. We discuss in detail the case, where the geometric phase is generat…
Decoherence of entangled kaons and its connection to entanglement measures
Reinhold A. Bertlmann, Katharina Durstberger, Beatrix C. Hiesmayr
We study the time evolution of the entangled kaon system by considering the Liouville - von Neumann equation with an additional term which allows for decoherence. We choose as gene…
