Controlling the transport of an ion: Classical and quantum mechanical solutions
H. A. Fürst, M. H. Goerz, U. G. Poschinger +6
We investigate the performance of different control techniques for ion transport in state-of-the-art segmented miniaturized ion traps. We employ numerical optimization of classical…
Noise Studies of Driven Geometric Phase Gates with Trapped Ions
A. Lemmer, A. Bermudez, M. B. Plenio
We present a study of the performance of the trapped-ion driven geometric phase gates introduced in [New J. Phys. 15, 083001 (2013)] when realized in a stimulated Raman transition.…
Extracting entanglement from identical particles
N. Killoran, M. Cramer, M. B. Plenio
Identical particles and entanglement are both fundamental components of quantum mechanics. However, when identical particles are condensed in a single spatial mode, the standard no…
Inverse counting statistics for stochastic and open quantum systems: the characteristic polynomial approach
M. Bruderer, L. D. Contreras-Pulido, M. Thaller +3
We consider stochastic and open quantum systems with a finite number of states, where a stochastic transition between two specific states is monitored by a detector. The long-time…
Competition between memory-keeping and memory-erasing decoherence channels
Tony J. G. Apollaro, Salvatore Lorenzo, Carlo Di Franco +2
We study the competing effects of simultaneous Markovian and non-Markovian decoherence mechanisms acting on a single spin. We show the existence of a threshold in the relative stre…
Strongly Coupled Diamond Spin Qubits by Molecular Nitrogen Implantation
Takashi Yamamoto, Christoph Müller, Liam P. McGuinness +7
Ionized nitrogen molecules (N) are used as efficient point sources for creating NV pairs in diamond with nanoscale spatial separation and up to 55 kHz magnetic c…
Ab-initio characterization of the quantum linear-zigzag transition using DMRG
Pietro Silvi, Tommaso Calarco, Giovanna Morigi +1
Ions of the same charge inside confining potentials can form crystalline structures which can be controlled by means of the ions density and of the external trap parameters. In par…
Quantifying Coherence
T. Baumgratz, M. Cramer, M. B. Plenio
We introduce a rigorous framework for the quantification of coherence and identify intuitive and easily computable measures of coherence. We achieve this by adopting the viewpoint…
