Atom microscopy via two-photon spontaneous emission spectroscopy RID A-5077-2009
(American Physical Society, 2009)
We study subwavelength position measurement via spontaneous emission spectroscopy with two photons. Our model systems are a single Lambda-type three-level atom, in which a dual interaction generates two independent photons, ...
Quantum teleportation of four-dimensional qudits
(American Physical Society, 2010)
A protocol for the teleportation of arbitrary quantum states of four-dimensional qudits is presented. The qudit to be teleported is encoded in the combined state of two ensembles of atoms placed in a cavity at the sender's ...
