A device for reducing the phase noise of a signal (S<SUB>in</SUB>), coming from a quasiperiodic source of fundamental frequency f<SUB>0</SUB>, comprises a superconducting circuit with an active line for voltage pulse transmission by transferring quanta of flux phi<SUB>0</SUB>. This circuit is defined so as to have a characteristic frequency f<SUB>c </SUB>such that 0.3 f<SUB>c</SUB>, is less than or equal to the fundamental frequency f<SUB>0 </SUB>of the quasiperiodic signal (S<SUB>in</SUB>) applied as input, and delivers, as output, a voltage pulse signal of fundamental frequency f<SUB>0</SUB>.
