Precision determination of the CKM element Vcb
Andrea Alberti, Paolo Gambino, Kristopher J. Healey +1
We extract the magnitude of the CKM matrix element Vcb and the most relevant parameters of the Heavy Quark Expansion from data of inclusive semileptonic B decays. Our calculation i…
Decoherence Models for Discrete-Time Quantum Walks and their Application to Neutral Atom Experiments
Andrea Alberti, Wolfgang Alt, Reinhard Werner +1
We discuss decoherence in discrete-time quantum walks in terms of a phenomenological model that distinguishes spin and spatial decoherence. We identify the dominating mechanisms th…
Digital atom interferometer with single particle control on a discretized spacetime geometry
Andreas Steffen, Andrea Alberti, Wolfgang Alt +5
Engineering quantum particle systems, such as quantum simulators and quantum cellular automata, relies on full coherent control of quantum paths at the single particle level. Here…
Ideal negative measurements in quantum walks disprove theories based on classical trajectories
Carsten Robens, Wolfgang Alt, Dieter Meschede +2
We report on a stringent test of the non-classicality of the motion of a massive quantum particle, which propagates on a discrete lattice. Measuring temporal correlations of the po…
