    "abstract": "Ghost imaging is a method to nonlocally image an object by transmitting pairs\nof entangled photons through the object and a reference optical system\nrespectively. We present a theoretical analysis of the quantum noise in this\nimaging technique. The dependence of the noise on the properties of the\napertures in the imaging system are discussed and demonstrated with a numerical\nexample. For a given source, the resolution and the signal-to-noise ratio\ncannot be improved at the same time .",
