1. A method for using one particle out of N particles for irradiating a target, comprising:providing a radiation source with N incoherent emitters;detecting radiation particles emitted from the radiation source by using N−1 detectors located at N−1 different positions; andopening a particle barrier based on an occurrence of single detections on all N−1 detectors within a predetermined time period to allow the one particle to reach the target. 2. The method according to claim 1, wherein the radiation particles are chosen from a group consisting of photons, phonons, electrons, protons, neutrons, alpha particles, atoms, molecules, and ions. 3. The method according to claim 1, wherein the emitters are chosen from a group consisting of atoms, ions, molecules, quantum dots, and Josephson circuits. 4. The method according to claim 1, wherein the emitters are arranged in a row. 5. The method according to claim 1, wherein the N−1 detectors are arranged in a plane which includes the radiation source. 6. The method according to claim 1, wherein at least one of the N−1 detectors is adapted to be movable during irradiation. 7. The method according to claim 1, wherein the N−1 detectors and the target are arranged at positions with respect to the radiation source so that a modulation of a signal generated by the accumulation of multiple detection events at the target takes a form of a pure sinus oscillation when at least the one detector and/or the particle barrier is moved. 8. The method according to claim 1, wherein at least one of the N−1 detectors and/or the particle barrier is moved circumferentially around the radiation source. 9. The method according to claim 8, wherein one of the N−1 detectors and the particle barrier are circumferentially moved around the radiation source in opposite angular directions with respect to each other. 10. The method according to claim 1, wherein radiation emitted by the emitters is scattered radiation caused by an application of radiation to said emitters by a second radiation source. 11. The method according to claim 10, wherein the radiation source is a pulsed radiation source. 12. The method according to claim 10, wherein not more than two energetic states of the emitters are selected in the scattering process. 13. The method according to claim 10, wherein the second radiation source is a laser. 14. The method according to claim 1, wherein the particle barrier is only locally opened. 15. The method according to claim 1, further comprising using a particle having passed the particle barrier for physical manipulation of a target by means of interaction between the particle and the target. 16. The method according to claim 1, wherein the irradiation of the target is used for lithography. 17. An apparatus for irradiating a target, comprising:a radiation source having N incoherent emitters;N−1 particle detectors located at N−1 different positions;a discriminator adapted for identifying single particle detection events on all N−1 detectors within a predetermined time period from other particle detection events; anda particle barrier adapted to be opened based on the discriminator. 18. The apparatus of claim 17, wherein the emitters are adapted to emit particles chosen from the group consisting of photons, phonons, electrons, protons, neutrons, alpha particles, atoms, molecules, and ions. 19. The apparatus of claim 17, wherein the emitters are chosen from the group consisting of atoms, ions, molecules, quantum dots, and Josephson circuits. 20. The apparatus of claim 17, further comprising a device adapted to maintain the positions of the emitters. 21. The apparatus of claim 17, wherein the N−1 detectors are arranged in a plane which includes the radiation source. 22. The apparatus of claim 17, further comprising a second radiation source. 23. The apparatus of claim 22, wherein the second radiation source is a pulsed radiation source. 24. The apparatus of claim 22, wherein the second radiation source is a laser. 25. The apparatus of claim 17, wherein at least one of the N−1 detectors is adapted to be movable during irradiation.
