    "abstract": "Detecting single atoms (qubits) is a key requirement for implementing quantum\ninformation processing on an atom chip. The detector should ideally be\nintegrated on the chip. Here we present and compare different methods capable\nof detecting neutral atoms on an atom chip. After a short introduction to\nfluorescence and absorption detection we discuss cavity enhanced detection of\nsingle atoms. In particular we concentrate on optical fiber based detectors\nsuch as fiber cavities and tapered fiber dipole traps. We discuss the various\nconstraints in building such detectors in detail along with the current\nimplementations on atom chips. Results from experimental tests of fiber\nintegration are also described. In addition we present a pilot experiment for\natom detection using a concentric cavity to verify the required scaling.",
