✦ Synopsis


A previous approximation scheme [6] which allowed to calculate, in a simple manner, the quantity An2/% (n mea.n value and An2 variance of the photon number) in the course of a multi-photon absorption process, is extended to study the change of the shape of the photon distribution, too. It turns out that there is a tendency to symmetrize the distribution. Moreover, an approrimative expression for the asymptotic distribution to which the distribution tends after a sufficiently strong absorption, irrespective of the initial distribution, is found in form of a Gaussian.

Der Einflufl der Mehr-Photonen-Absorption auf die Photonenstatistik

I n h a l tsubersicht. Ein friiheres Naheningsverfahren [6], das in einfacher Weise die GroDo An2/% (G Mittelwert und An* quadratische Streuung der Photonenzahl) im Verlauf eines Mehr-Photonen-A bsorptionsprozesses zu berechnen gestattet, wird zum Zweck der Untersuchung der Anderung der Gestalt, der Photonenverteilung weiterentwickelt. Es zeigt sich, da13 eine Tendenz zur Symmetrisierung der Verteilung besteht. Dariiber hinaus wird ein Kaherungsausdruck fiir die asymptotische Verteilung, der die Vcrteilung nach hinreichend starker Absorption unabhangig von der Ausgangsverteilung zustrebt, in Gestalt einer GauD-Verteilung angegeben.

We examine several proposed schemes by Franson et al. for quantum logic gates based on non-local exchange interactions between two photons in a medium. In these schemes the presence of a single photon in a given mode is supposed to induce a large phase shift on another photon propagating in the same
