Quantum-limited position measurements of a dark matter-wave soliton
Antonio Negretti, Carsten Henkel, Klaus Molmer
We show that the position of a dark matter-wave soliton can be determined with a precision that scales with the atomic density as . This surpasses the standard shot-noise…
Quantum computing with a single molecular ensemble and a Cooper pair box
Karl Tordrup, Klaus Molmer
We propose to encode quantum information in rotational excitations in a molecular ensemble. Using a stripline cavity field for quantum state transfer between the molecular ensemble…
Atomic diffraction in counter-propagating Gaussian pulses of laser light
Tapio P. Simula, Atom Muradyan, Klaus Molmer
We present an analysis of atomic diffraction due to the interaction of an atomic beam with a pair of Gaussian light pulses. We derive a simple analytical expression for the populat…
Geometric phases in open tripod systems
Ditte Moller, Lars Bojer Madsen, Klaus Molmer
We first consider stimulated Raman adibatic passages (STIRAP) in a closed four-level tripod system. In this case, the adiabatic eigenstates of the system acquire real geometric pha…
Hanbury Brown and Twiss correlations in atoms scattered from colliding condensates
Klaus Molmer, A. Perrin, V. Krachmalnicoff +4
Low energy elastic scattering between clouds of Bose condensed atoms leads to the well known s-wave halo with atoms emerging in all directions from the collision zone. In this pape…
Quantum computing with collective ensembles of multi-level systems
E. Brion, K. Moelmer, M. Saffman
We propose a new physical approach for encoding and processing of quantum information in ensembles of multi-level quantum systems, where the different bits are not carried by indiv…
