Optimal quantum radar vs. optimal classical radar with full polarization antennas
Fred E. Daum, Arjang Noushin, Jim Huang · 2021
We compute the optimal quantum radar detection performance relative to the corresponding optimal classical radar detection performance with full polarization antennas. We use the Belavkin-Zakai equation rather than the Schrödinger equation, because the latter does not have an explicit measurement model. Our calculation is consistent with the well known 6 dB quantum advantage at low photon flux per mode assuming no polarization entanglement of photons and no use of fully polarized antennas.
