A Hidden Markov Model of atomic quantum jump dynamics in an optically probed cavity
S. Gammelmark, W. Alt, T. Kampschulte +2
We analyze the quantum jumps of an atom interacting with a cavity field. The strong atom- field interaction makes the cavity transmission depend on the time dependent atomic state,…
The Fisher information and the quantum Cramer-Rao sensitivity limit of continuous measurements
Søren Gammelmark, Klaus Mølmer
Precision measurements with quantum systems rely on our ability to trace the differences between experimental signals to variations in unknown physical parameters. In this Letter w…
Dipoles on a Two-leg Ladder
Søren Gammelmark, Nikolaj Thomas Zinner
We study polar molecules with long-range dipole-dipole interactions confined to move on a two-leg ladder for different orientations of the molecular dipole moments with respect to…
Past quantum states
Søren Gammelmark, Brian Julsgaard, Klaus Mølmer
A density matrix ρ(t) yields probabilistic information about the outcome of measurements on a quantum system. We introduce here the past quantum state, which, at time T, accounts f…
