Coherent inelastic backscattering of laser light from three isotropic atoms
Andreas Ketterer, Andreas Buchleitner, Vyacheslav N. Shatokhin
We study the impact of double and triple scattering contributions on coherent backscattering of laser light from saturated isotropic atoms, in the helicity preserving polarization…
Quantum search with modular variables
A. Ketterer, T. Douce, A. Keller +2
We give a dimension independent formulation of the quantum search algorithm introduced in [L. K. Grover, Phys. Rev. Lett. {\bf 79}, 325 (1997)]. This algorithm provides a quadratic…
Quantum information with modular variables
A. Ketterer, S. P. Walborn, A. Keller +2
We introduce a novel strategy, based on the use of modular variables, to encode and deterministically process quantum information using states described by continuous variables. Ou…
Quantum search with non--orthogonal entangled states
T. Douce, A. Ketterer, A. Keller +2
We propose a classical to quantum information encoding system using non--orthogonal states and apply it to the problem of searching an element in a quantum list. We show that the p…
Testing the Clauser-Horne-Shimony-Holt inequality using observables with arbitrary spectrum
A. Ketterer, A. Keller, T. Coudreau +1
The Clauser-Horne-Shimony and Holt inequality applies when measurements with binary outcomes are performed on physical systems under the assumption of local realism. Testing such i…
