Energy-time entangled photon pairs exhibit at the same time narrowband and short time features. We show how to make use of those quantum properties to realize measurements beyond the capabilities of classical devices. As proof of principle experiment we show imaging through a scattering medium by selecting the ballistic photons only, using optical coincidence measurements.

Conference Presentations are recordings of oral presentations given at SPIE conferences and published as part of the proceedings. They include the speaker's narration with video of the slides and animations. Most include full-text papers. Interactive, searchable transcripts and closed captioning are now available for most presentations.
