Resum
| Descripció |
English: In new NIST experiments, the 'color' (wavelength) of photons from a quantum dot single photon source (QD SPS) is changed to a more convenient shade using an up-conversion crystal and pump laser. To test that the process truly acts on single photons without degrading the signal (by creating additional photons), the output is split in two and sent to parallel detectors-true single photons should not be detected simultaneously in both paths.
