Atomic-position localization via dual measurement Academic Article uri icon


  • We study localization of atomic position when a three-level atom interacts with a quantized standing-wave field in the Ramsey interferometer setup. Both the field quadrature amplitude and the atomic internal state are measured to obtain the atomic-position information. It is found that this dual-measurement scheme produces an interference pattern superimposed on a diffractionlike pattern in the atomic-position distribution, where the former pattern originates from the state-selective measurement and the latter from the field measurement. The present scheme results in a better resolution in the position localization than the field-alone measurement schemes. We also discuss the measurement-correlated mechanical action of the standing-wave field on the atom in the light of Popper’s test. © 2002 The American Physical Society.
