Ghost imaging is accessible in the undergraduate laboratory. However, the advantage of ghost imaging over regular imaging is difficult to quantify. We searched for a simple example that can be quantified with basic statistics. Using classical computational ghost imaging, we find that the signal-to-noise ratio for ghost imaging of a slit (the object) can exceed that of regular imaging with the same exposure of the slit when the detectors are sufficiently noisy. This result is obtained by numerical simulation and by theoretical analysis. We discuss an experiment using the typical spontaneous down conversion source for entangled photons as used in quantum physics education kits to demonstrate this imaging advantage.
