7.A similar interferometer was independently considered by Sakaki, H. Sakaki, private communication (unpublished).
8.To externally modulate the relative phase difference it is essential that each electron propagates through two subband states rather than a single sub‐band state, because the relative phase is fixed for the latter. This point was sometimes disregarded: e.g., Fig. 2 of
8.N. Tsukada, A. D. Wieck, and K. Ploog, Appl. Phys. Lett. 56, 2527 (1990). Their devices are also subject to strong degradations due to multimode transmissions.
