Prospects for storage and retrieval of a quantum dot single photon in an ultracold Rb ensemble
Matthew T. Rakher, Richard J. Warburton, Philipp Treutlein
Epitaxially grown quantum dots (QDs) are promising sources of non-classical states of light such as single photons and entangled photons. However, in order for them to be used as a…
Sequential quantum-enhanced measurement with an atomic ensemble
A. V. Lebedev, P. Treutlein, G. Blatter
We propose a quantum-enhanced iterative (with steps) measurement scheme based on an ensemble of two-level probes which asymptotically approaches the Heisenberg limit $δ_K \…
Quantum metrology with a scanning probe atom interferometer
Caspar F. Ockeloen, Roman Schmied, Max F. Riedel +1
We use a small atomic Bose-Einstein condensate as an interferometric scanning probe to map out a microwave field near a chip surface with a few micrometers resolution. Using entang…
Cavity-Enhanced Long-Distance Coupling of an Atomic Ensemble to a Micromechanical Membrane
B. Vogell, K. Stannigel, P. Zoller +5
We discuss a hybrid quantum system where a dielectric membrane situated inside an optical cavity is coupled to a distant atomic ensemble trapped in an optical lattice. The coupling…
