    "abstract": "We propose a new technique, called quantum optical coherence tomography\n(QOCT), for carrying out tomographic measurements with dispersion-cancelled\nresolution. The technique can also be used to extract the frequency-dependent\nrefractive index of the medium. QOCT makes use of a two-photon interferometer\nin which a swept delay permits a coincidence interferogram to be traced. The\ntechnique bears a resemblance to classical optical coherence tomography (OCT).\nHowever, it makes use of a nonclassical entangled twin-photon light source that\npermits measurements to be made at depths greater than those accessible via\nOCT, which suffers from the deleterious effects of sample dispersion. Aside\nfrom the dispersion cancellation, QOCT offers higher sensitivity than OCT as\nwell as an enhancement of resolution by a factor of 2 for the same source\nbandwidth. QOCT and OCT are compared using an idealized sample.",
