Abstract: Emerging technologies based on quantum state engineering of ultracold matter and precise control of the laser field have revolutionized a new generation of optical atomic clocks with accuracy at the 18th digit. This progress has benefited greatly from microscopic understandings of atomic interactions in the quantum regime and the capability of controling optical phase coherence over many seconds. The unified front of precision metrology and quantum physics will allow us to explore complex qluantum systems, test the fundamental laws of nature, search for new physics, and find unexpected applications.
