The advantages of using quantum states of light for object detection are often highlighted in schemes that use simultaneous and optimal measurements. Here, we describe a theoretical but experimentally realizable quantum illumination scheme based on non-simultaneous and non-optimal measurements which can maintain this advantage. In particular, we examine the multi-click heralded two mode squeezed vacuum state as a probe signal in a quantum illumination process. The increase in conditioned signal intensity associated with multi-click heralding is greater than that from a single detector-heralded signal. Our results show, for lossy external conditions, the presence of the target object can be revealed earlier using multi-click measurements. We demonstrate this through sequential shot measurements based on Monte-Carlo simulation.
