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,…
Optical lattice quantum Hall effect
Rebecca N. Palmer, Alexander Klein, Dieter Jaksch
We explore the behavior of interacting bosonic atoms in an optical lattice subject to a large artificial magnetic field. We extend earlier investigations of this system where the n…
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…
