“…This requires previous knowledge of the target range [52,49,15,54,5]. Because of this constrain, it has been suggested the use of quantum illumination once the target range is known, as a scanner system or in bio-medical applications [49,5,46]. The advantage of quantum illumination over classical illumination can be exploded for having better resolution of the structure of possible targets, once the target has been located by other means.…”

“…A practical advantage is that a JPA generator allows partial modulation of the generated frequencies by modulation of the pump frequency. This is a mechanism that allows to partially determine the range of the target for short distance radar or for scanning applications [46]. The main problem is the practical implementation of the cryogenic conditions.…”

After a brief introduction to the notion of quantum entanglement and quantum correlations, several schemes for a quantum radar based upon the quantum illumination and others protocols are discussed. We review different concepts that have been introduced to overcome several of the inherent difficulties in the implementation of quantum generation and/or detection of quantum sensing protocols for RADAR applications. Our review is an up-to date critical presentation of the state of the art, with emphasis in the case by case assessment of the feasibility of the different concepts. We also aim that the review is accessible to non-experts in the field. Hence several appendixes and a technical glossary are included.

“…This implies that the quantum illumination with two-mode Gaussian state gives much less error probability compared to that with the classical coherent state. The quantum illumination with two-mode Gaussian state was extended to the asymmetric Gaussian hypothesis testing [21,22]. Also, the quantum illumination with non-Gaussian initial state generated by photon subtraction and addition was also discussed [23,24].…”

The 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 ρ (state for target absence) and σ (state for target presence) is less than the previous result derived by two-mode Gaussian state when N S , average photon number per signal, is less than 0.295. This indicates that the quantum illumination with three-mode Gaussian state gives less error probability compared to that with two-mode Gaussian state when N S < 0.295.
