Complete sets of cyclic mutually unbiased bases in even prime power dimensions
Oliver Kern, Kedar S. Ranade, Ulrich Seyfarth
We present a construction method for complete sets of cyclic mutually unbiased bases (MUBs) in Hilbert spaces of even prime power dimensions. In comparison to usual complete sets o…
Feedback-Optimized Operations with Linear Ion Crystals
J. F. Eble, S. Ulm, P. Zahariev +2
We report on transport operations with linear crystals of 40Ca+ ions by applying complex electric time-dependent potentials. For their control we use the information obtained from…
Fabrication of a planar micro Penning trap and numerical investigations of versatile ion positioning protocols
M. Hellwig, A. Bautista-Salvador, K. Singer +2
We describe a versatile planar Penning trap structure, which allows to dynamically modify the trapping conguration almost arbitrarily. The trap consists of 37 hexagonal electrodes,…
Focusing a deterministic single-ion beam
Wolfgang Schnitzler, Georg Jacob, Robert Fickler +2
We focus down an ion beam consisting of single 40Ca+ ions to a spot size of a few mum using an einzel-lens. Starting from a segmented linear Paul trap, we have implemented a proced…
Critical properties of homogeneous binary trees
P. Silvi, V. Giovannetti, S. Montangero +3
Many-body states whose wave-function admits a representation in terms of a uniform binary-tree tensor decomposition are shown to obey to power-law two-body correlations functions.…
Colloquium: Trapped ions as quantum bits -- essential numerical tools
Kilian Singer, Ulrich Poschinger, Michael Murphy +4
Trapped, laser-cooled atoms and ions are quantum systems which can be experimentally controlled with an as yet unmatched degree of precision. Due to the control of the motion and t…
