Decoherence of matter waves by thermal emission of radiation
Lucia Hackermueller, Klaus Hornberger, Bjoern Brezger +2
Emergent quantum technologies have led to increasing interest in decoherence - the processes that limit the appearance of quantum effects and turn them into classical phenomena. On…
The wave nature of biomolecules and fluorofullerenes
Lucia Hackermueller, Stefan Uttenthaler, Klaus Hornberger +4
We demonstrate quantum interference for tetraphenylporphyrin, the first biomolecule exhibiting wave nature, and for the fluorofullerene C60F48 using a near-field Talbot-Lau interfe…
Remote preparation of a single-mode photonic qubit by measuring field quadrature noise
S. A. Babichev, B. Brezger, A. I. Lvovsky
An electromagnetic field quadrature measurement, performed on one of the modes of the nonlocal single-photon state , collapses it into a superposition of the single-…
Decoherence in a Talbot Lau interferometer: the influence of molecular scattering
Lucia Hackermueller, Klaus Hornberger, Bjoern Brezger +2
We study the interference of C70 fullerenes in a Talbot-Lau interferometer with a large separation between the diffraction gratings. This permits the observation of recurrences of…
Experimental Vacuum Squeezing in Rubidium Vapor via Self-Rotation
J. Ries, B. Brezger, A. I. Lvovsky
We report the generation of optical squeezed vacuum states by means of polarization self-rotation in rubidium vapor following a proposal by Matsko et al. [Phys. Rev. A 66, 043815 (…
Collisional decoherence observed in matter wave interferometry
Klaus Hornberger, Stefan Uttenthaler, Bjoern Brezger +3
We study the loss of spatial coherence in the extended wave function of fullerenes due to collisions with background gases. From the gradual suppression of quantum interference wit…
