Recently invented and demonstrated optical lattice clocks hold great promise for improving the precision of modern time keeping. These clocks aim at the 10{sup -18} fractional accuracy, which translates into a clock that would neither lose nor gain a fraction of a second over an estimated age of the Universe. In these clocks, millions of atoms are trapped and interrogated simultaneously, dramatically improving clock stability. Here the principles of operation of these clocks are discussed and, in particular, a novel concept of magic trapping of atoms in optical lattices. Recently proposed microwave lattice clocks are also highlights and several applications that employ the optical lattice clocks as a platform for precision measurements and quantum information processing.

• Hunting for topological dark matter with atomic clocks (2013, background): “The minimum time between consecutive measurements is determined by several factors: in lattice clocks [72], this would be an atomic ensemble preparation time (about 1 second), in microwave fountain clocks [73] it the time of flight across interrogation chamber (also about 1 second).”
