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…
Infinite qubit rings with maximal nearest neighbor entanglement: the Bethe ansatz solution
U. V. Poulsen, T. Meyer, D. Bruss +1
We search for translationally invariant states of qubits on a ring that maximize the nearest neighbor entanglement. This problem was initially studied by O'Connor and Wootters [Phy…
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…
Can optical squeezing be generated via polarization self-rotation in a thermal vapour cell?
M. T. L. Hsu, A. Dantan, J. Cviklinski +9
The traversal of an elliptically polarized optical field through a thermal vapour cell can give rise to a rotation of its polarization axis. This process, known as polarization sel…
Single-passage read-out of atomic quantum memory
J. Fiurasek, J. Sherson, T. Opatrny +1
A scheme for retrieving quantum information stored in collective atomic spin systems onto optical pulses is presented. Two off-resonant light pulses cross the atomic medium in two…
