Interference of cavity light by a single atom acting as a double slit (2023)
Journal Article

Young's double-slit interference experiment is central to quantum mechanics. While it has been demonstrated that an array of atoms can produce interference in light, it is a fundamental question to ask whether a single atom can act as a double slit w...
