摘要: We theoretically investigate the wave–particle duality based on a Raman atom interferometer, via the interaction between the atom and Raman laser, which is similar to the optical Mach–Zehnder interferometer. The wave and which-way information are stored in the atomic internal states. For the φ-π-π/2 type of atom interferometer, we find that the visibility (V) and predictability (P) still satisfy the duality relation, P2+V2 ≤ 1.
