Object identification and tracking by quantum radar
Quantum Technologies and Quantum Information Science V, 2019 Quantum Radar is a promising technology that could have a strong impact on the civilian and military realms. In this study we introduce a new concept design for implementing a Quantum Radar, based on the time and polarization correlations of the entangled photons for detection and identification and tracking of high-speed targets. The design is focused

Entanglement Sustainability in Quantum Radar [PDF]
IEEE Journal of Selected Topics in Quantum Electronics, 2020 Quantum radar is generally defined as a detection sensor that utilizes the microwave photons like a classical radar. At the same time, it employs quantum phenomena to improve detection, identification, and resolution capabilities. However, the entanglement is so fragile, unstable, and difficult to create and to preserve for a long time.

Demonstration of Quantum Advantage in Microwave Quantum Radar
Nature Physics, 2022 While quantum entanglement can enhance the performance of several technologies such as computing, sensing and cryptography, its widespread use is hindered by its sensitivity to noise and losses. Interestingly, even when entanglement has been destroyed, some tasks still exhibit a quantum advantage $Q$, defined by a $Q$-time speedup, over any classical ...

Fourier Expression of the Quantum Radar Cross Section of a Dihedral Corner Reflector
IEEE Photonics Journal, 2021 In this paper, a Fourier expression of the quantum radar cross section (QRCS) of a dihedral corner reflector is proposed, which avoids the problems caused by atomic sampling on the target-object surface and is a powerful tool for analyzing the scattering

On Entanglement-Assisted Multistatic Radar Techniques
Entropy, 2022 Entanglement-based quantum sensors have much better sensitivity than corresponding classical sensors in a noisy and lossy regime. In our recent paper, we showed that the entanglement-assisted (EA) joint monostatic–bistatic quantum radar performs much ...
