The Importance of Precise Timekeeping

Precise timekeeping is essential for many modern technologies. Atomic clocks are the most accurate way to measure time, but even they have limitations. This slide highlights the importance of precise timekeeping in our daily lives.

How Atomic Clocks Work

 Atomic clocks use the natural oscillations of atoms to keep time. In a strontium atomic clock, a laser beam interacts with strontium atoms, causing them to vibrate at a specific frequency. This frequency is used to define the second.

Limitations of Current Atomic Clocks

The laser used to read the oscillation of atoms in atomic clocks heats up the atoms. Hot atoms escape the clock, which reduces precision. To maintain accuracy, atomic clocks constantly need to be replaced with fresh atoms.

Superradiance: A New Approach

Superradiance is a quantum phenomenon where a group of atoms emit light together. Researchers are exploring using superradiance to read the oscillation of atoms in atomic clocks. This method would heat the atoms minimally, potentially improving precision.

Benefits of More Precise Atomic Clocks

More precise atomic clocks could lead to more accurate GPS systems, improved navigation for future space missions, and new scientific discoveries.

GPS and Superradiant Atomic Clocks

Atomic clocks in GPS satellites are essential for determining location. More precise atomic clocks could improve the accuracy of GPS systems.

Superradiant Atomic Clocks and Space Exploration

Future space missions will require even more precise timekeeping.
