Stabilization of quantum information by combined dynamical decoupling and detected-jump error correction
Daniel Geberth, Oliver Kern, Gernot Alber +1
Two possible applications of random decoupling are discussed. Whereas so far decoupling methods have been considered merely for quantum memories, here it is demonstrated that rando…
Complex chaos in conditional qubit dynamics and purification protocols
T. Kiss, I. Jex, G. Alber +1
Selection of an ensemble of equally prepared quantum systems, based on measurements on it, is a basic step in quantum state purification. For an ensemble of single qubits, iterativ…
The Jamiołkowski isomorphism and a conceptionally simple proof for the correspondence between vectors having Schmidt number and -positive maps
Kedar S. Ranade, Mazhar Ali
Positive maps which are not completely positive are used in quantum information theory as witnesses for convex sets of states, in particular as entanglement witnesses and more gene…
Coherent manipulation of atomic qubits in optical micropotentials
A. Lengwenus, J. Kruse, M. Volk +2
We experimentally demonstrate the coherent manipulation of atomic states in far-detuned dipole traps and registers of dipole traps based on two-dimensional arrays of microlenses. B…
Perfect state transfer in networks of arbitrary topology and coupling configuration
V. Kost'ak, G. M. Nikolopoulos, I. Jex
A general formalism of the problem of perfect state transfer is presented. We show that there are infinitely many Hamiltonians which may provide solution to this problem. In a firs…
