    "abstract": "We study two different decoherence modes for entangled qubits by considering\na Liouville - von Neumann master equation. Mode A is determined by projection\noperators onto the eigenstates of the Hamiltonian and mode B by projectors onto\nrotated states. We present solutions for general and for Bell diagonal states\nand calculate for the later the mixedness and the amount of entanglement given\nby the concurrence.\n  We propose a realization of the decoherence modes within neutron\ninterferometry by applying fluctuating magnetic fields. An experimental test of\nthe Kraus operator decomposition describing the evolution of the system for\neach mode is presented.",
