Decoherence measurement of single phonons using spectral interference
F. C. Waldermann, B. J. Sussman, J. Nunn +9
A technique to measure the decoherence time of optical phonons in a solid is presented. Phonons are excited with a pair of time delayed 80 fs, near infrared pulses via spontaneous,…
Self-trapping of impurities in Bose-Einstein condensates: Strong attractive and repulsive coupling
M. Bruderer, W. Bao, D. Jaksch
We study the interaction-induced localization -- the so-called self-trapping -- of a neutral impurity atom immersed in a homogeneous Bose-Einstein condensate (BEC). Based on a Hart…
Dynamics, dephasing and clustering of impurity atoms in Bose-Einstein condensates
Alexander Klein, Martin Bruderer, Stephen R. Clark +1
We investigate the influence of a Bose-Einstein condensate (BEC) on the properties of immersed impurity atoms, which are trapped in an optical lattice. Assuming a weak coupling of…
A quantum repeater based on decoherence free subspaces
Uwe Dorner, Alexander Klein, Dieter Jaksch
We study a quantum repeater which is based on decoherence free quantum gates recently proposed by Klein et al. [Phys. Rev. A 73, 012332 (2006)]. A number of operations on the decoh…
Creating diamond color centers for quantum optical applications
F. C. Waldermann, P. Olivero, J. Nunn +10
Nitrogen vacancy (NV) centers in diamond have distinct promise as solid-state qubits. This is because of their large dipole moment, convenient level structure and very long room-te…
Dynamics of vortices in weakly interacting Bose-Einstein condensates
Alexander Klein, Dieter Jaksch, Yanzhi Zhang +1
We study the dynamics of vortices in ideal and weakly interacting Bose-Einstein condensates using a Ritz minimization method to solve the two-dimensional Gross-Pitaevskii equation.…
