My 40+ Years in Quantum Optical Communication
Shapiro, Jeffrey - MIT
Presentation on Thursday, May 2, 2019, 7 a.m.
Location: MIT Room 6C-442
I have spent 40+ years working on a variety of topics in quantum optical communication. In this talk, I will present a semi-chronological, incomplete review of how that field has progressed, focusing on some of my group’s contributions. The results to be presented are: the quantum theory of diffraction; semiclassical versus quantum photodetection and the Yuen-Shapiro representation theorem; perturbation theory versus the Gaussian-state description of spontaneous parametric downconversion; phase-sensitive coherence and its application to ghost imaging and imaging with undetected photons; the chi-3 nonlinearity in the single-photon limit; and the quantum illumination story.
