Quantum entanglement in the lab


The recent and rapid progress in the field of quantum technologies stimulates developments of specific courses and experimental training for future engineers and scientists. We describe below the experimental setup developed at Institut d’Optique Graduate School for engineering and Master students. During a labwork session afternoon, students can study a source of polarization entangled state pairs of photons and perform an experimental violation of Bell’s inequalities. This emblematic experiment is one of the experiments dedicated to quantum photonics. It was built in 2005 in the LEnsE (the Laboratoire d’Enseignement Experimental) of the Institut d’Optique Graduate School and has been perfectly working for almost eighteen years already.
