Cold-atom microwave clocks represent a significant advancement in precise timekeeping. These devices harness the quantum properties of cold atoms, typically cesium or rubidium, to maintain an exceptionally accurate and stable frequency standard. The process involves cooling the atoms to near absolute zero temperatures, significantly reducing their thermal motion. This minimal motion allows for more precise measurements of microwave transitions between the quantum states of the atoms, essential for applications requiring the utmost accuracy, such as global positioning systems (GPS) and advanced scientific research.
In this session, Patrick Berthoud will chair a series of presentations focused on the latest research in cold-atom microwave clocks, conducted in collaboration with partners from government, industry and academia. Speakers will explore various technologies that enhance the accuracy, stability and reliability of these precision timekeeping devices. Additionally, they will discuss how the insights gained from this research are being applied to practical, real-world applications, highlighting the impact of these advancements across different sectors.
