    "abstract": "We present a technique for state-selective position detection of cold Rydberg\natoms. Ground state Rb atoms in a magneto-optical trap are excited to a Rydberg\nstate and are subsequently ionized with a tailored electric field pulse. This\npulse selectively ionizes only atoms in e.g. the 54d state and not in the 53d\nstate. The released electrons are detected after a slow flight towards a micro\nchannel plate. From the time of flight of the electrons the position of the\natoms is deduced. The state selectivity is about 20:1 when comparing 54d with\n53d and the one-dimensional position resolution ranges from 6 to 40 $\\mu$m over\na range of 300 $\\mu$m. This state selectivity and position resolution are\nsufficient to allow for the observation of coherent quantum excitation\ntransport.",
