Tóm tắt

This paper analyzes, theoretically, an atomic double-slit interferometer in order to probe the extent to which complementary properties affect quantum interference. It is shown that if the energy eigenstates of a two-level atom are one-to-one correlated with its particle and wave behaviors, complementary phenomena can be measured simultaneously, indicating a reinterpretation of the complementarity principle. We also demonstrate that these complementary properties can be further distinguished by using a post-selection process.
