Abstract
In a two-particle interferometer, one can study the variation of both single- and joint-detection probabilities as functions of the phase shifts of the beams. By combining the usual definition for one-particle fringe visibility (i=1,2) with a reasonable proposed definition for two-particle fringe visibility , we show that +≤1 or, equivalently, ≤1/2. Some extensions are discussed.
