Patrick Berthoud chairs cold-atom microwave clock discussions at EFTF 2024

Session will focus on the results of four scientific papers concerned with improving accuracy, stability and reliability of cold-atom microwave clocks

  • Speakers: Patrick Berthoud, time and frequency chief scientist at Oscilloquartz, Adtran
  • Topics: Cold-atom microwave clocks
  • When: Wednesday, June 26, 10:30 a.m. CET
  • Where: 37th European Frequency and Time Forum (EFTF), University of Neuchâtel, Neuchâtel, Switzerland 

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.
