Quantum state tomography of molecular rotation
Anders S. Mouritzen, Klaus Molmer
We show how the rotational quantum state of a linear or symmetric top rotor can be reconstructed from finite time observations of the polar angular distribution under certain condi…
Fidelities for transformations of unknown quantum states
Lars Bojer Madsen, Klaus Molmer
We present a general theoretical formalism to compute the fidelity of transformations of unknown quantum states. We then focus on the case of Gaussian transformations of continuous…
Tomographic reconstruction of quantum states in N spatial dimensions
Anders S. Mouritzen, Klaus Molmer
Most quantum tomographic methods can only be used for one-dimensional problems. We show how to infer the quantum state of a non-relativistic N-dimensional harmonic oscillator syste…
Continuous measurements on continuous variable quantum systems: The Gaussian description
L. B. Madsen, K. Mølmer
The Gaussian state description of continuous variables is adapted to describe the quantum interaction between macroscopic atomic samples and continuous-wave light beams. The formal…
Gaussian State Description of Squeezed Light
Vivi Petersen, Lars Bojer Madsen, Klaus Molmer
We present a Gaussian state description of squeezed light generated in an optical parametric oscillator. Using the Gaussian state description we describe the dynamics of the system…
