Detector-Agnostic Phase-Space Distributions
J. Sperling, D. S. Phillips, J. F. F. Bulmer +11
The representation of quantum states via phase-space functions constitutes an intuitive technique to characterize light. However, the reconstruction of such distributions is challe…
Incomplete Detection of Nonclassical Phase-Space Distributions
M. Bohmann, J. Tiedau, T. Bartley +3
We implement the direct sampling of negative phase-space functions via unbalanced homodyne measurement using click-counting detectors. The negativities significantly certify noncla…
Verifying bound entanglement of dephased Werner states
P. Thomas, M. Bohmann, W. Vogel
The verification of quantum entanglement under the influence of realistic noise and decoherence is crucial for the development of quantum technologies. Unfortunately, a full entang…
Quantifying nonclassicality by characteristic functions
S. Ryl, J. Sperling, W. Vogel
In this paper, we use the characteristic function, i.e., the Fourier transform of the Glauber-Sudarshan phase-space distribution, to find the degree of nonclassicality of a given s…
Anomalous Quantum Correlations of Squeezed Light
B. Kühn, W. Vogel, M. Mraz +2
Three different noise moments of field strength, intensity, and their correlations are simultaneously measured. For this purpose a homodyne cross-correlation measurement [W. Vogel,…
Identification of nonclassical properties of light with multiplexing layouts
J. Sperling, A. Eckstein, W. R. Clements +9
In a recent contribution, we introduced and applied a detector-independent method to uncover nonclassicality. Here, we extend those techniques and give more details on the performe…
