Abstract
Control system () for a state of a quantum harmonic oscillator, comprising: —a harmonic oscillator () in a Schrödinger's cat type state, —a stabilisation device () with a predetermined parity of a number of bosons of the state, which device is configured to use first and second frequency combs each comprising at least as many rays as a mean number of bosons in the state, and —a multiphonic dissipation device () which is suitable for removing at least one pair of bosons simultaneously from the oscillator, the dissipation device being activated only between two successive time peaks of the frequency combs over a time period greater than the inverse of the product of the mean number and the inverse of the characteristic time of the multiphonic dissipation, a time period separating two activation periods being less than a characteristic loss time of a boson.
