Effective second-order correlation function and single-photon detection
Peter Grünwald
Quantum-optical research on semiconductor single-photon sources puts special emphasis on the measurement of the second-order correlation function , arguing that $g^{(2)…
Nonclassical light from an incoherently pumped quantum dot in a microcavity
L. Teuber, P. Grünwald, W. Vogel
Semiconductor microcavities with artificial single-photon emitters have become one of the backbones of semiconductor quantum optics. In many cases however, technical and physical i…
Quantum Measurement of Broadband Nonclassical Light Fields
P. Grünwald, D. Vasylyev, J. Häggblad +1
Based on the measurement of quantum correlation functions, the quantum statistical properties of spectral measurements are studied for broadband radiation fields. The spectral filt…
Quantum-entangled light from localized emitters
P. Grünwald, W. Vogel
Localized radiation sources are analyzed with respect to the relation of nonclassicality and quantum entanglement of the emitted light. The source field parts of the radiation emit…
Enhanced squeezing by absorption
P. Grünwald, W. Vogel
Absorption is usually expected to be detrimental to quantum coherence effects. However, the situation for complex absorption spectra has been little studied yet. We consider the re…
Superfluorescence spectra of excitons in quantum wells
P. Grünwald, G. K. G. Burau, H. Stolz +1
We study the fluorescence light emitted from GaAs excitons in semiconductor quantum wells. The excitons are modeled as interacting bosons. By combining quantum optical methods for…
Optimal Squeezing in the Resonance Fluorescence of Single Photon Emitters
P. Grünwald, W. Vogel
Annual Review of Astronomy and Astrophysics, Volume 51, page 511e studied for coherently driven single photon sources, such as atoms and quantum dots. Maximal squeezing is realized…
Entanglement in atomic resonance fluorescence
P. Grünwald, W. Vogel
The resonance fluorescence from regular atomic systems is shown to represent a continuous source of non-Gaussian entangled radiation propagating in two different directions. For a…
The statistical strength of nonlocality proofs
Wim van Dam, Peter Grunwald, Richard Gill
There exist numerous proofs of Bell's theorem, stating that quantum mechanics is incompatible with local realistic theories of nature. Here we define the strength of such nonlocali…
