    Nonclassical OCT images biological sample
    Quantum optical coherence tomography (OCT) has, for the first time, been shown to be a viable biological imaging technique, says M. Boshra Nasr, a postdoctoral researcher in the Quantum Imaging Laboratory at Boston University (Boston, MA). Nasr led a project that has produced the first experimental quantum OCT (QOCT) images of a biological sample. Quantum OCT holds strong appeal because, unlike classical OCT, it is inherently immune to group-velocity dispersion (GVD), which degrades axial resolution.1 This immunity is a direct result of the frequency entanglement inherent in the light source used in such a scheme; QOCT is a fourth-order ...
