The world of timekeeping is advancing rapidly, and the newest development is the comparison of spin-squeezed optical lattice clocks. This new technology promises to improve the accuracy and stability of timekeeping devices, and has been developed by a team at the National Institute of Standards and Technology (NIST). The team compared a traditional atomic clock based on a single atom, to a spin-squeezed optical lattice clock, which is based on a lattice of thousands of atoms.

The team found that the spin-squeezed optical lattice clock was more accurate, with an error rate of less than one part in 10^17. This is an incredibly small error rate, and is an order of magnitude better than the traditional atomic clock. The team also found that the spin-squeezed optical lattice clock was more stable, meaning it could keep time more accurately over longer periods of time. This new technology could revolutionize the way we keep time, and could have a wide range of applications, from navigation to communication.
