Abstract: We identify the physical origin of the loss of interference pattern in the which-path atom-interferometery experiments that have been discussed widely. The origin of complementarity between the which-path information and the interference pattern is a discrete spinor phase with random sign. This clarifies how complementarity can arise without the Heisenberg back action in momentum.
