The behaviors of fundamental particles at the atomic and sub-atomic levels governed by the laws of quantum physics are often mystifying. At these levels, particles can become strongly correlated and stay entangled even when they are separated far apart. Such extraordinary property not only entices our scientific minds to delve deeper into the discovery of new principles and phenomena in science, it also opens up an array of new opportunities to explore these phenomena to applied science and technology. Our aim is to advance the study of matters in the quantum realm of the atomic and sub-atomic length scales, in the fields of quantum science, AMO physics, and low-dimensional system.
