Figure

FIG. 1. (a) Photon pair Source: Photon pairs correlated in time and wavelength are generated through SPDC by a 405 nm CW laser pumping a nonlinear crystal
FIG. 2. (a) Histogram of 200 s integration time showing the number of events detected as a function of arrival time difference T between the signal and heralding photons using only T correlations.
FIG. 3. Experimentally measured and theoretically predicted SBR (blue dashed line) and SNR (red solid line) enhancement factors as a function of the width of the S correlation selection band.
FIG. 6. (a) Every row of the spectral correlation band is horizon- horizon-tally shifted such that they form a vertical band

In order to have an accurate way to correct time error between the two receivers, a synchronization protocol has been developed, based on the periodic emission of a

practices or acts that transcendentally condition the possibility of all other social practices. Let us nevertheless reflect briefly on the relation of the sub-categories of gift

There fore, ~~ their sugges tion, It was ~eeided to test an alte rna te cognitive technique , guide d imagery , in order to determine whether this method would provide a more

Contrarily to classical audio features like MFCC, we make the hypothesis that histograms of gradients are able to encode some relevant informations in a time-frequency

The predicted covariance structure depends on the readout parameters, and in particular on the temporal integration window w and typical number of neurons K used in the formation of

The comparison of the traveltimes estimated from positive and negative time surface waves allows us to distinguish the fluctuations due to any form of physical change in the medium

Among the nine available data (three axes for each of the three sensors), we chose to use only 2 of them: the accelerometer z-axis and the gyroscope z-axis.. A
