Atomic systems, having the advantage of possessing universal properties, are widely used in quantum sensors requiring absolute accuracy, such as atomic clocks. In particular, leveraging matter wave interference in Bose-Einstein condensates (BECs) allow for “macroscopic” observation of quantum effects that are typically attributed to the physical phenomena of single atoms. Atomic physics experiments at KRISS are introduced which are geared towards precision metrology by utilizing the amplification of quantum signatures with BECs. Furthermore, we explore ways to generate, control, and measure quantum states in atomic and nanomechanical systems which can lead to enhanced quantum sensing.
