Researchers present the first heralded generation of photon states that are maximally entangled in polarization with linear optics. Three photon pairs are generated by spontaneous parametric down-conversion from β-barium borate crystals. The coincident detection of four auxiliary photons unambiguously heralds the successful preparation of the entangled state.
