Paper Abstract

Currently there is interest in the possibility of using quantum-mechanically entangled light to enhance the spatial resolution of sensors. Here I review some applications of equations in quantum-mechanical form to the design of sensors and related systems. In order to consider comparing equations against experiments, we will need to distinguish models comprised of mathematical formulas, whether quantum-mechanical or classical, from experiments with devices such as lasers and light detectors. The following sections sketch: * two known ways to connect quantum models to experiments (one statistical-mechanical, the other by way of probabilities); * an approximate way to translate from equations of classical electromagnetism to the quantum language of photons and detection probabilities, concentrating on interferometric effects; * quantum-mechanically suggested possibilities and obstacles for light-based radar (lidar) to enhance positional accuracy and spatial resolution; * a recently proved universal gap between, on one hand, quantum-mechanical models composed of equations and, on the other hand, experiments with devices, with the consequent need and opportunities for a designer to choose models as descriptions of measured behavior.
