The AIT developed equipment for the generation of pairs of entangled photons. This dynamic system, in which different parameters such as photon number, wavelength, and coherence length can be adapted to the client's needs, was developed for use in teaching at the university, but also for research facilities needing entanglement as the basis for scientific experiments. The device generates up to 5,000 photon pairs per second.


  • Single photon rate: 3.5 MHz/(s mW) in single mode fiber
  • Coincidence rate: 1.4 MHz/(s mW) in single mode fiber
  • Bandwidth: 130 GHz
  • Brightness: 10 MHz/(s mW THz)
  • Visibility: ~90%
