In this paper we propose and realise a practical quantum enhanced sensing protocol aimed at the detection of a partially reflecting object in a lossy and noisy environment. Our scheme is inspired by the theoretical quantum illumination protocol elaborated by Lloyd (2008 Science 321 , 1463) and Tan et al (2008 Phys. Rev. Lett. 101 , 253601). We demonstrate that when only photon counting is allowed our quantum protocol performs astonishingly better than the best classical counterpart.
