摘要: We present measurements of the polarization correlation and photon statistics pairs that emerge from a laser-pumped warm rubidium vapor cell. The occur at 780 nm 1367 are entangled. measure autocorrelation each generated fields as well cross-correlation function, observe strong violation two-beam Cauchy-Schwartz inequality. evaluate performance system source heralded single photons telecommunication wavelength. see coincidences suppressed by factor ≈ 20 Poissonian generation rate 1500 s−1, heralding efficiency 10%, narrow spectral width.
