Abstract
One Hermitian operator and one non-Hermitian operator are introduced for the predictability and visibility in a two-way interferometer. The sum of the variances of the predictability and visibility is used to measure the uncertainty, which is linked to the complementarity relation through the equation, (ΔP)2 + (ΔVf)2 + P2 + V2 = 2.
