Quantum Illumination with Multiple Entangled Photons [PDF]
Advanced Quantum Technologies, 2021 Abstract 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 to signal‐to‐noise ratio (SNR) and reduces the required time‐bandwidth product to have the

Feedback-enabled microwave quantum illumination
Quantum Science and Technology, 2022 Abstract A simple feedback scheme can be used to operate efficiently a microwave-quantum-illumination device based on electro-optomechanical systems also in regimes in which excess dissipation would, otherwise, prevent to outperform the optimal classical illumination protocol with the same transmitted energy.

Quantum illumination receiver using double homodyne detection
Physical Review Research, 2021 A quantum receiver is an essential element of quantum illumination (QI), which outperforms its classical counterpart, called classical illumination. However, there are only few proposals for realizable quantum receiver, which exploits nonlinear effects ...

Classical benchmarking for microwave quantum illumination
IET Quantum Communication, 2021 Quantum illumination theoretically promises up to a 6 dB error‐exponent advantage in target detection over the best classical protocol. The advantage is maximised by a regime that includes a very high background, which occurs naturally when one considers

Investigation of the JPA-Bandwidth Improvement in the Performance of the QTMS Radar
Entropy, 2023 Josephson parametric amplifier (JPA) engineering is a significant component in the quantum two-mode squeezed radar (QTMS) to enhance, for instance, radar performance and the detection range or bandwidth.

Quantum illumination assistant with error-correcting codes
New Journal of Physics, 2020 We scheme how to enhance the detection ability of quantum target recognition without using entanglement resources. Based on the commonly used error-correcting codes and corresponding decoding method, our scheme gives lower error probability and higher ...

How discord underlies the noise resilience of quantum illumination
New Journal of Physics, 2016 The benefits of entanglement can outlast entanglement itself. In quantum illumination, entanglement is employed to better detect reflecting objects in environments so noisy that all entanglement is destroyed.
