Quantum fluctuations in the image of a Bose gas
Antonio Negretti, Carsten Henkel, Klaus Molmer
We analyze the information content of density profiles for an ultracold Bose gas of atoms and extract resolution limits for observables contained in these images. Our starting poin…
A Wave Function approach to dissipative processes
Yvan Castin, Jean Dalibard, Klaus Molmer
Due to growing interest in quantum measurement, control and feedback, we reproduce a manuscript from 1992, presenting a simple physical and mathematical derivation of stochastic di…
Atomic spin squeezing in an optical cavity
Anne E. B. Nielsen, Klaus Molmer
We consider squeezing of one component of the collective spin vector of an atomic ensemble inside an optical cavity. The atoms interact with a cavity mode, and the squeezing is obt…
Holographic quantum computing
Karl Tordrup, Antonio Negretti, Klaus Molmer
We propose that a single mesoscopic ensemble of trapped polar molecules can support a "holographic quantum computer" with hundreds of qubits encoded in collective excitations with…
Two-channel Feshbach physics in a structured continuum
N. Nygaard, R. Piil, K. Molmer
We analyze the scattering and bound state physics of a pair of atoms in a one-dimensional optical lattice interacting via a narrow Feshbach resonance. The lattice provides a struct…
Stochastic master equation for a probed system in a cavity
Anne E. B. Nielsen, Klaus Molmer
We present a detailed derivation of the stochastic master equation determining the time evolution of the state of a general quantum system, which is placed inside a cavity and subj…
