Incoherent dynamics in the toric code subject to disorder
Beat Röthlisberger, James R. Wootton, Robert M. Heath +2
We numerically study the effects of two forms of quenched disorder on the anyons of the toric code. Firstly, a new class of codes based on random lattices of stabilizer operators i…
A witness for topological order and stable quantum memories in abelian anyonic systems
James R. Wootton
We propose a novel parameter, the anyonic topological entropy, designed to detect the error correcting phase of a topological memory. Unlike similar quantities such as the topologi…
Dependence of a quantum mechanical system on its own initial state and the initial state of the environment it interacts with
Adrian Hutter, Stephanie Wehner
We present a unifying framework to the understanding of when and how quantum mechanical systems become independent of their initial conditions and adapt macroscopic properties (lik…
Spectroscopy of mechanical dissipation in micro-mechanical membranes
Andreas Jöckel, Matthew T. Rakher, Maria Korppi +4
We measure the frequency dependence of the mechanical quality factor (Q) of SiN membrane oscillators and observe a resonant variation of Q by more than two orders of magnitude. The…
Quantum-control approach to realizing a Toffoli gate in circuit QED
Vladimir M. Stojanovic, A. Fedorov, A. Wallraff +1
We study the realization of a Toffoli gate with superconducting qubits in a circuit-QED setup using quantum-control methods. Starting with optimized piecewise-constant control fiel…
libCreme: An optimization library for evaluating convex-roof entanglement measures
Beat Röthlisberger, Jörg Lehmann, Daniel Loss
We present the software library libCreme which we have previously used to successfully calculate convex-roof entanglement measures of mixed quantum states appearing in realistic ph…
Realization of an optomechanical interface between ultracold atoms and a membrane
Stephan Camerer, Maria Korppi, Andreas Jöckel +3
We have realized a hybrid optomechanical system by coupling ultracold atoms to a micromechanical membrane. The atoms are trapped in an optical lattice, which is formed by retro-ref…
Quantum simulation of the hexagonal Kitaev model with trapped ions
Roman Schmied, Janus H. Wesenberg, Dietrich Leibfried
We present a detailed study of quantum simulations of coupled spin systems in surface-electrode ion-trap arrays, and illustrate our findings with a proposed implementation of the h…
The Influence of Geometry on the Vibronic Spectra of Quantum Aggregates
A. Eisfeld, G. Schulz, J. S. Briggs
A study is presented of the localisation of excitonic states on extended molecular aggregates composed of identical monomers arising, not from disorder due to statistical energy sh…
Temperature-independent quantum logic for molecular spectroscopy
J. Mur-Petit, J. Pérez-Ríos, J. Campos-Martínez +3
We propose a fast and non-destructive spectroscopic method for single molecular ions that implements quantum logic schemes between an atomic ion and the molecular ion of interest.…
Schrieffer-Wolff transformation for quantum many-body systems
Sergey Bravyi, David DiVincenzo, Daniel Loss
The Schrieffer-Wolff (SW) method is a version of degenerate perturbation theory in which the low-energy effective Hamiltonian H_{eff} is obtained from the exact Hamiltonian by a un…
Quantum computing implementations with neutral particles
Antonio Negretti, Philipp Treutlein, Tommaso Calarco
We review quantum information processing with cold neutral particles, that is, atoms or polar molecules. First, we analyze the best suited degrees of freedom of these particles for…
Nondeterminstic ultrafast ground state cooling of a mechanical resonator
Yong Li, Lian-Ao Wu, Ying-Dan Wang +1
We present an ultrafast feasible scheme for ground state cooling of a mechanical resonator via repeated random time-interval measurements on an auxiliary flux qubit. We find that t…
Coupling ultracold atoms to mechanical oscillators
David Hunger, Stephan Camerer, Maria Korppi +3
In this article we discuss and compare different ways to engineer an interface between ultracold atoms and micro- and nanomechanical oscillators. We start by analyzing a direct mec…
Tomographic reconstruction of the Wigner function on the Bloch sphere
Roman Schmied, Philipp Treutlein
We present a filtered backprojection algorithm for reconstructing the Wigner function of a system of large angular momentum j from Stern-Gerlach-type measurements. Our method is ad…
