text: Quantum illumination is a sensing technique that employs entangled signal-idler
beams to improve the detection efficiency of low-reflectivity objects in environments
with large thermal noise. The advantage over classical strategies is evident at
low signal brightness, a feature which could make the protocol an ideal prototype
for non-invasive scanning or low-power short-range radar. Here we experimentally
investigate the concept of quantum illumination at microwave frequencies, by generating
entangled fields using a Josephson parametric converter which are then amplified
to illuminate a room-temperature object at a distance of 1 meter. Starting from
experimental data, we simulate the case of perfect idler photon number detection,
which results in a quantum advantage compared to the relative classical benchmark.
Our results highlight the opportunities and challenges on the way towards a first
room-temperature application of microwave quantum circuits.
