Characterization of two-particle interference by complementarity

Bohr's Complementarity Principle is quantitatively formulated in terms of the distinguishability various paths a quanton can take, and measure interference it produces. This phenomenon results from single-quanton amplitudes for paths. The puts bound on sharpness produce. However there exist other kinds quantum phenomena where two-particle interference, if particles are indistinguishable. Hong-Ou-Mandel (HOM) effect Hanbury-Brown-Twiss (HBT) two well known examples. However, not as easy to define its single particle counterpart, realization that involves amplitudes, came much later. In this work, duality relation, between visibility derived. particles, arising some internal degree freedom, they produce, HOM or HBT kind experiment. It argued existence complementarity be used characterize which turn leads one conclusion effects equivalent essence, may treated phenonmenon.
