From High Precision to Innovation: Optical Lattice Clocks for Future Applications

Optica Distinguished Lecture Series on Quantum Science and Technology

Optical lattice clocks achieve 18-digit accuracy, enabling chronometric leveling and paving the way for redefining the second. Advances in compact clock designs, long-distance clock comparisons and continuous interrogation techniques will facilitate their real-world implementation.

About the Speaker

Hidetoshi Katori, born 27 September 1964, is a Japanese physicist and professor at the University of Tokyo best known for having invented the magic wavelength technique for ultra-precise optical lattice atomic clocks. Since 2011, Katori is also Chief Scientist at the Quantum Metrology Lab, RIKEN.

Recently, Katori's group performed a measurement of gravitational redshift with two transportable strontium optical lattice clocks over nearly the entire height of the Tokyo Skytree, setting a new record for the best ground-based test of general relativity.
