Abstract: A method for measurement of a sequence of recurring electronic signals (10) is proposed, wherein the sequence to be measured consists of n recurring electronic signals, wherein a time-to-digital converter (2) and a memory (5) are provided.

Abstract: A method is proposed for generating single photons with a predetermined wavelength fV, with the following steps: i) generating a single photon, preferably in a source and a resonator, wherein the single photon has a resonator wavelength fR and a resonator bandwidth fBR, ii) measuring the resonator wavelength fR, preferably in a wavelength standard, wherein the single photon is guided from the resonator to the wavelength standard via a beam guide, iii) comparing the resonator wavelength fR with the predetermined wavelength fV and generating a control signal on the basis of the comparison, preferably in a controller, iv) adjusting the resonator using the control signal in order to change the resonator wavelength fR toward or to the predetermined wavelength fV, v) repeating steps i to iv) until the resonator wavelength fR corresponds to the predetermined wavelength fV and then coupling out.
