Quantum Radar with Genuine Tripartite Entanglement.

Quantum radar is a remote sensing technique for target detection that has extensively been explored in conjunction with entangled two-mode squeezed vacuum states. This work extends the existing protocol to a scheme that utilizes a three-mode squeezed state with genuine tripartite entanglement. The three entangled modes are divided into two signal modes and one idler mode. A numerical evaluation of the Chernoff bound shows that the proposed protocol has the potential to offer a higher quantum advantage in specific parameter regimes.
