• Abstract: Detection of low-reflectivity objects can be improved by the so-called quantum illumination procedure. However, quantum detection probability exponentially decays with the source bandwidth. The Josephson Parametric Amplifiers (JPAs) technology utilized as a source, generating a pair of entangled signals called two-mode squeezed vacuum states, shows a very narrow bandwidth limiting the operation of the microwave quantum radar (MQR). In this paper, for the first time, a microwave quantum radar setup based on quantum illumination protocol and using a Josephson Traveling Wave Parametric Amplifier (JTWPA) is proposed. Measurement results of the developed JTWPA, pumped at 12 GHz, show an ultrawide bandwidth equal to 10 GHz at X-band making our MQR a promising candidate for the detection of stealth objects.

  In this paper, an explicit expression for the maximum detection range of an entangled quantum two-mode squeezed (QTMS) radar has been derived. We show that one can view a QTMS radar as a traditional radar with a reduced threshold signal-to-noise ratio. It is possible to implement a QTMS radar with a maximum detection range of up to 2km, which is suitable for recognizing small unmanned aerial vehicles at urban distances.
