More precisely, we calculate the error for symmetric and asymmetric error settings and compare the performance of two-mode squeezed vacuum states (quantum illumination) and coherent states (a laser). For symmetric error setting the coherent state error is slightly lower than this of quantum illumination. For asymmetric error setting, the unstable phase of ToF changes the scaling of the information loss from one over the transmission to one over the transmission square, significantly limiting the maximal detected range.
