and quantum theory of measurement; quantum chaos; high-precision measurements. These themes lead not only to a better understanding of fundamental phenomena, but also to important applications, like more precise atomic clocks, improvement of detectors based on atomic interferometry or new methods for biomedical imaging.

The laboratory also has an important activity in the field of measurement of fundamental constants and tests of fundamental physical theories (quantum electrodynamics, gravitation, strong interaction). It holds records of precision in the measurement of certain fundamental constants. The LKB is also
