To generate entangled photons, a commercial optical system was used (quED, qutools.com, Munich, Germany). This apparatus sends a blue laser beam through a nonlinear crystal to produce pairs of red photons with entangled polarizations. The strength of entanglement was determined by measuring correlations between the polarizations of pairs of photons. To do this, each photon [...]
