    "abstract": "Quantum optical coherence tomography (Q-OCT) offers a factor-of-two\nimprovement in axial resolution and the advantage of even-order dispersion\ncancellation when it is compared to conventional OCT (C-OCT). These features\nhave been ascribed to the non-classical nature of the biphoton state employed\nin the former, as opposed to the classical state used in the latter.\nPhase-conjugate OCT (PC-OCT), introduced here, shows that non-classical light\nis not necessary to reap Q-OCT\u0027s advantages. PC-OCT uses classical-state signal\nand reference beams, which have a phase-sensitive cross-correlation, together\nwith phase conjugation to achieve the axial resolution and even-order\ndispersion cancellation of Q-OCT with a signal-to-noise ratio that can be\ncomparable to that of C-OCT.",
