| Abstract: | Over the last decade, implementations of single photon detector (SPD) technology have improved across a wide range of figures of merit. In this talk, we will explore the construction of three-stage photo detection POVMs that are sufficiently idealized to have wide applicability across SPD platforms, and also sufficiently realistic to capture tradeoffs and fundamental limits to SPD figures of merit that experimentalists may encounter. In the first stage of photodetection, an incident photon is transmitted into the SPD. Next, that single excitation is amplified into a macroscopic signal via a nonlinear amplification mechanism. Finally, a noisy classical measurement is performed on the amplified signal, resulting in a POVM from which SPD figures of merit can be calculated. | |
