Generation and detection of a sub-Poissonian atom number distribution in a one-dimensional optical lattice
J. -B. Béguin, E. Bookjans, S. L. Christensen +4
We demonstrate preparation and detection of an atom number distribution in a one-dimensional atomic lattice with the variance dB below the Poissonian noise level. A mesoscopi…
Quantum interference of a single spin excitation with a macroscopic atomic ensemble
S. L. Christensen, J. -B. Béguin, E. Bookjans +4
We report on the observation of quantum interference of a collective single spin excitation with a spin ensemble of atoms. Detection of a single photon scat…
Towards quantum state tomography of a single polariton state of an atomic ensemble
S. L. Christensen, J. B. Béguin, H. L. Sørensen +5
We present a proposal and a feasibility study for the creation and quantum state tomography of a single polariton state of an atomic ensemble. The collective non-classical and non-…
Atomic nonclassicality quasiprobabilities
T. Kiesel, W. Vogel, S. L. Christensen +3
Although nonclassical quantum states are important both conceptually and as a resource for quantum technology, it is often difficult to test whether a given quantum system displays…
