This frequency comb is fundamental in quantum applications based on ion traps. Its function is to transfer the optical frequency reference of the calcium ion, 729 nm, to other applications, such as the reference of the Cesium standard, to give traceability to the unit of length by measuring the wavelength of standard lasers by the frequency beating technique, to provide traceability to the quantum voltage patterns in direct and alternating current or in the establishment of a quantum communications network.
