COMBINED QUANTUM FREQUENCY STANDARD Russian patent published in 2023 - IPC H03L7/26 

FIELD: quantum frequency standards.

SUBSTANCE: quantum frequency standard is proposed, containing the first ring of automatic frequency control (AFC), including a series-connected adjustable crystal oscillator, signal conditioner of a radio-frequency excitation of a rubidium gas cell (RGC), a quantum discriminator on a rubidium gas cell, a RGC control voltage composer, its output is connected to the first input of the cumulating counter, and the second ring of the AFC of the adjustable crystal oscillator contains a series-connected unit for reference signal conditioner of an atomic-beam tube (ABT), its input is connected to the output of the adjustable crystal oscillator, a signal conditioner of ABT radio-frequency excitation, a quantum discriminator on ABT, its output is connected to the signal input of the ABT control voltage composer, its output is connected to the second input of the cumulating counter.

EFFECT: development of a quantum frequency standard with two parallel operable rings of automatic frequency adjustment of an adjustable crystal oscillator.
