Abstract
We show that it is possible to associate a de Broglie wavelength to a compo site system even when the constituent particles are separated spatially. Th e nonlocal de Broglie wavelength (lambda /2) of a two-photon system separat ed spatially is measured with an appropriate detection system. The two-phot on system is prepared in an entangled state in space-momentum variables.
