Comparing Homodyne and Heterodyne Tomography of Quantum States of Light
Rhea P. Fernandes, Andrew J. Pizzimenti, Christos N. Gagatsos +1
Non-Gaussian quantum states are critical resources in photonic quantum information processing, rendering their generation and characterization of increasing importance in quantum o…
Optimal single-mode squeezing for beam displacement sensing
Wenhua He, Christos N. Gagatsos, Dalziel J. Wilson +1
Estimation of an optical beam's transverse displacement is a canonical imaging problem fundamental to numerous optical imaging and sensing tasks. Quantum enhancements to the measur…
Bayesian Greedy Receiver for Pulse Position Modulation without an Error Floor under Thermal Noise
Leo Bia, Christos N. Gagatsos, Saikat Guha
We investigate quantum receiver architectures for demodulation -ary Pulse Position Modulation under thermal noise and photon-starved conditions. Building on the greed receiver f…
Heralded enhancement in quantum state discrimination
Qipeng Qian, Christos N. Gagatsos
The discrimination of quantum states is a central problem in quantum information science and technology. Meanwhile, partial post-selection has emerged as a valuable tool for quantu…
Fundamental Limits Of Quickest Change-point Detection With Continuous-Variable Quantum States
Tiju Cherian John, Christos N. Gagatsos, Boulat A. Bash
We generalize the quantum CUSUM (QUSUM) algorithm for quickest change-point detection, analyzed in finite dimensions by Fanizza, Hirche, and Calsamiglia (Phys. Rev. Lett. 131, 0206…
