Single-Atom Cavity QED and Opto-Micromechanics
M. Wallquist, K. Hammerer, P. Zoller +6
In a recent publication [K. Hammerer et al., Phys. Rev. Lett. 103, 063005 (2009)] we have shown the possibility to achieve strong coupling of the quantized motion of a micron-sized…
Bell's experiment with intra- and inter-pair entanglement: Single-particle mode entanglement as a case study
S. Ashhab, Koji Maruyama, Caslav Brukner +1
Theoretical considerations of Bell-inequality experiments usually assume identically prepared and independent pairs of particles. Here we consider pairs that exhibit both intra- an…
Quantifying entanglement with covariance matrices
Oleg Gittsovich, Otfried Gühne
Covariance matrices are a useful tool to investigate correlations and entanglement in quantum systems. They are widely used in continuous variable systems, but recently also for fi…
Intra-molecular refrigeration in enzymes
Hans J. Briegel, Sandu Popescu
We present a simple mechanism for intra-molecular refrigeration, where parts of a molecule are actively cooled below the environmental temperature. We discuss the potential role an…
Entanglement of mechanical oscillators coupled to a non-equilibrium environment
Max Ludwig, K. Hammerer, Florian Marquardt
Recent experiments aim at cooling nanomechanical resonators to the ground state by coupling them to non-equilibrium environments in order to observe quantum effects such as entangl…
Not all pure entangled states are useful for sub shot-noise interferometry
Philipp Hyllus, Otfried Gühne, Augusto Smerzi
We investigate the connection between the shot-noise limit in linear interferometers and particle entanglement. In particular, we ask whether or not sub shot-noise sensitivity can…
