NONLOCAL INTERFEROMETRY WITH HIGH-INTENSITY FIELDS

Two-photon interferometry can produce violations of Bell's inequality that demonstrate the nonlocal nature of such effects. It is shown here that high-intensity fields containing large numbers of photons can violate Bell's inequality in a similar manner. The macroscopic nature of these fields is evident from the fact that they can produce large bursts of energy in two distant absorbers with nonlocal correlations between the two.
