Columbia’s atomic and molecular experts explore the quantum states of atoms and molecules and how these particles interact. To do so, we are developing new techniques and tools to precisely capture and control individual atoms and molecules.
Our work has important implications for expanding our knowledge about atomic, molecular, and even fundamental physics, as well as applications in quantum optics and novel devices, like quantum simulators and quantum computers.
