of the experiments in ( 26–29 ), wherein polar- ization entanglement is generated via post se- lection (see supporting online text and Fig. 4C). The mapping is performed assuming that quan- tum mechanics is correct ( 1 , 27–29 ). At t 0 0, the predicted CHSH Bell _ s parameter is S 0 2.68(2), a violation of the Bell _ sinequality k S k e 2. The predicted violation is not closer to the the- oretical maximum S max 0 2 ffiffi 2 p , 2 : 828 (dashed line of Fig. 4C), largely due to backgrounds set by the two-photon generation rate. The frequency bandwidths of the write and read photons are 1.1(2) MHz, making them ideal for interacting with narrowband systems such as atoms, molecules, and optical cavities. By separately heterodyning the write and read photons with laser light derived from the p - pump laser (measured linewidth of 50 kHz), we obtained the power spectral density of the pho- tons from the Fourier transform of the measured second-order autocorrelation function (Fig. 4D). The photons are nearly Fourier-transform limited, as can be seen from the 2-MHz full width at half-maximum power spectrum (Fig. 4E) of the measured cross-correlation function g wr ( t ) taken at slightly different parameters. These measurements show that pairs of
