Quantum Illumination with Multiple Entangled Photons [PDF]

Advanced Quantum Technologies, 2021
Art. 2100101, 9 S.In this work, a theoretical generalization of Lloyd's quantum illumination model for signal beams described by two entangled photon states is developed. It is shown that the new protocol is more sensitive than Lloyd's model with respect

Quantum Estimation Methods for Quantum Illumination [PDF]

Physical Review Letters, 2017
Quantum illumination consists in shining quantum light on a target region immersed in a bright thermal bath with the aim of detecting the presence of a possible low-reflective object.

Minimum error probability of quantum illumination [PDF]

Physical Review A, 2018
Quantum illumination is a technique for detecting the presence of a target in a noisy environment by means of aquantum probe. We prove that the two-mode squeezed vacuum state is the optimal probe for quantum illuminationin the scenario of asymmetric ...

Bi‐Frequency Illumination: A Quantum‐Enhanced Protocol

Advanced Quantum Technologies, 2022
Abstract Quantum‐enhanced, idler‐free sensing protocol to measure the response of a target object to the frequency of a probe in a noisy and lossy scenario is proposed. In this protocol, a target with frequency‐dependent reflectivity embedded in a thermal bath is considered. The aim is to estimate the parameter ,

Quantum illumination with three-mode Gaussian state [PDF]

Quantum Information Processing, 2022
AbstractThe quantum illumination is examined by making use of the three-mode maximally entangled Gaussian state, which involves one signal and two idler beams. It is shown that the quantum Bhattacharyya bound between $$\rho $$ ρ (state for target absence) and $$\sigma $$ σ (state for

Quantum Illumination: A Laboratory Investigation

2018 International Carnahan Conference on Security Technology (ICCST), 2018
Quantum illumination is an idea for detection of targets in the presence of a noisy background using a photon pair that is entangled in some degree of freedom, such as frequency. This paper provides a simple and illustrative proof-of-concept setup of a quantum illumination investigation. Detection and imaging is investigated in the optical regime using
