Journal ArticleDOI
Experimental multiparticle entanglement dynamics induced by decoherence
Julio T. Barreiro,Philipp Schindler,Otfried Gühne,Otfried Gühne,Otfried Gühne,Thomas Monz,M. Chwalla,Christian F. Roos,Christian F. Roos,Markus Hennrich,Rainer Blatt,Rainer Blatt +11 more
TL;DR: In this article, a noisy environment is used to study the dynamics of a four-trapped-ion entangled state and it is shown that entanglement properties such as distillability and separability can be altered by controlling the degree of dephasing.
Journal ArticleDOI
Efficient tomography of a quantum many-body system

Buyskikh,Andrew J. Daley,Marcus Cramer,Marcus Cramer,Martin B. Plenio,Rainer Blatt,Rainer Blatt,Christian F. Roos,Christian F. Roos +21 more
TL;DR: In this article, the authors used matrix product state tomography (MPST) to reconstruct the dynamical state of a trapped-ion quantum simulator comprising up to 14 entangled and individually controlled spins.
Journal ArticleDOI
Laser addressing of individual ions in a linear ion trap
Hanns-Christoph Nägerl,Dietrich Leibfried,H. Rohde,Gregor Thalhammer,Jürgen Eschner,Ferdinand Schmidt-Kaler,Rainer Blatt +6 more
TL;DR: In this paper, single-quantum bit operations for quantum information processing with trapped ions are shown to be feasible with a tightly focused laser beam and an acousto-optic deflector, and the excitation into a long-lived metastable level is detected with a quantum jump technique.
Journal ArticleDOI
Trapped-ion probing of light-induced charging effects on dielectrics
TL;DR: In this article, a string of confined 40Ca+ ions is used to measure perturbations to a trapping potential which are caused by the light-induced charging of an antireflection-coated window and of insulating patches on the ion-trap electrodes.
Journal ArticleDOI
Preparation of Fock states by observation of quantum jumps in an ion trap.
TL;DR: In this paper, a technique for the preparation of Fock states of a harmonic oscillator strongly coupled to a single two-level atomic transition based on the observation of quantum jumps is proposed.
