Hybrid Topological Quantum Computation with Majorana Fermions: A Cold Atom Setup
C. Laflamme, M. A. Baranov, P. Zoller +1
In this paper we present a hybrid scheme for topological quantum computation in a system of cold atoms trapped in an atomic lattice. A topological qubit subspace is defined using M…
Topology by dissipation
C. -E. Bardyn, M. A. Baranov, C. V. Kraus +4
Topological states of fermionic matter can be induced by means of a suitably engineered dissipative dynamics. Dissipation then does not occur as a perturbation, but rather as the m…
Braiding of Atomic Majorana Fermions in Wire Networks and Implementation of the Deutsch-Josza Algorithm
Christina V. Kraus, P. Zoller, Mikhail A. Baranov
We propose an efficient protocol for braiding atomic Majorana fermions in wire networks with AMO techniques and demonstrate its robustness against experimentally relevant errors. B…
A time-dependent variational principle for dissipative dynamics
Christina V. Kraus, Tobias J. Osborne
We extend the time-dependent variational principle to the setting of dissipative dynamics. This provides a locally optimal (in time) approximation to the dynamics of any Lindblad e…
Generalized Hartree Fock Theory for Dispersion Relations of Interacting Fermionic Lattice Systems
Christina V. Kraus, Tobias J. Osborne
We study the variational solution of generic interacting fermionic lattice systems using fermionic Gaussian states and show that the process of "gaussification", leading to a nonli…
Generating topological order from a 2D cluster state using a duality mapping
Benjamin J. Brown, Wonmin Son, Christina V. Kraus +2
In this paper we prove, extend and review possible mappings between the two-dimensional Cluster state, Wen's model, the two-dimensional Ising chain and Kitaev's toric code model. W…
