Entangled photon pairs from radiative cascades in semiconductor quantum dots

We use polarization tomography to demonstrate for the first time entanglement between photon pairs from the biexciton radiative cascade. The entangled pair violates Bellpsilas inequality and satisfies Peres criterion by more than 3 standards deviations of the experimental uncertainty.
