Full-Period Optical Phase Estimation with Heisenberg Scaling Using Displaced Squeezed States and Gaussian Measurements
Marco A. RodrÃguez-GarcÃa, Luis Medina-Dozal, Francisco E. Becerra
We propose two-stage optimized strategies for full-period optical phase estimation with single-mode Gaussian states and Gaussian measurements under a fixed energy constraint. In th…

Effects of multi-photon states in the calibration of single-photon detectors based on a portable bi-photon source
Sujeet Pani, Duncan Earl, Francisco Elohim Becerra
Single-photon detectors (SPDs) are ubiquitous in many protocols for quantum imaging, sensing, and communications. Many of these protocols critically depend on the precise knowledge…
