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…
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…
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…
Quantum-limited position measurements of a dark matter-wave soliton
Antonio Negretti, Carsten Henkel, Klaus Molmer
We show that the position of a dark matter-wave soliton can be determined with a precision that scales with the atomic density as . This surpasses the standard shot-noise…
Quantum computing with a single molecular ensemble and a Cooper pair box
Karl Tordrup, Klaus Molmer
We propose to encode quantum information in rotational excitations in a molecular ensemble. Using a stripline cavity field for quantum state transfer between the molecular ensemble…
