Entanglement of two atomic samples by quantum non-demolition measurements
Antonio Di Lisi, Klaus Moelmer
This paper presents simulations of the state vector dynamics for a pair of atomic samples which are being probed by phase shift measurements on an optical beam passing through both…
Quantum interference with photon pairs created in spatially separated sources
H. de Riedmatten, I. Marcikic, W. Tittel +2
We report on a quantum interference experiment to probe the coherence between two photons coming from non degenerate photon pairs at telecom wavelength created in spatially separat…
Qubits from Number States and Bell Inequalities for Number Measurements
Jan-Åke Larsson
Bell inequalities for number measurements are derived via the observation that the bits of the number indexing a number state are proper qubits. Violations of these inequalities ar…
Narrowband frequency tunable light source of continuous quadrature entanglement
Christian Schori, Jens L. Sørensen, Eugene S. Polzik
We report the observation of non-classical quantum correlations of continuous light variables from a novel type of source. It is a frequency non-degenerate optical parametric oscil…
Blackbody-radiation-assisted molecular laser cooling
I. S. Vogelius, L. B. Madsen, M. Drewsen
The translational motion of molecular ions can be effectively cooled sympathetically to temperatures below 100 mK in ion traps through Coulomb interactions with laser-cooled atomic…
Trapped-Ion Quantum Logic Utilizing Position-Dependent ac Stark Shifts
Peter Staanum, Michael Drewsen
We present a scheme utilizing position-dependent ac Stark shifts for doing quantum logic with trapped ions. By a proper choice of direction, position and size, as well as power and…
