    "abstract": "We experimentally demonstrate shaping of the two-photon wavefunction of\nentangled photon-pairs, utilizing coherent pulse-shaping techniques. By\nperforming spectral-phase manipulations we tailor the two-photon wavefunction\nexactly like a coherent ultrashort pulse. To observe the shaping we perform\nsum-frequency generation (SFG) with an ultrahigh flux of entangled photons. At\nthe appropriate conditions, SFG performs as a coincidence detector with an\nultrashort response time (~100 fs), enabling a direct observation of the\ntwo-photon wavefunction. This property also enables us to demonstrate\nbackground-free, high-visibility two-photon interference oscillations.",
