Reversed interplay of quantum interference and which-way information in multi-photon entangled states

Young-Sik Ra, Malte C. Tichy, Hyang-Tag Lim +4

We report experimental studies of the multi-photon quantum interference of a two-mode three-photon entangled Fock state $|2,1⟩$ + $|1,2⟩$ impinging on a two-port bala…
