Proceedings ArticleDOI
Progress toward an optical frequency standard based on a single indium ion
Yanhui Wang,Tao Liu,Rainer Dumke,A. Stejskal,Y. N. Zhao,L. J. Wang,Thomas Becker,Herbert Walther +7 more
TL;DR: In this paper, a single indium ion is trapped and cooled via sideband cooling to its lowest vibrational states to measure the 115In+ 1S 0 -3P 0 clock transition with high accuracy.
Journal ArticleDOI
Field fluctuations measured by interferometry
TL;DR: In this paper, the complete photon count statistics of an interferometer based on two beam splitters were derived based on the transformation properties of state vectors as well as field operators at a beam splitter.
Journal ArticleDOI
Microwave ionization of Rb Rydberg atoms: Frequency dependence.
Leszek Sirko,Leszek Sirko,Markus Arndt,Markus Arndt,P. M. Koch,P. M. Koch,Herbert Walther,Herbert Walther +7 more
TL;DR: Physical arguments are given based on experimental data and previous experimental and theoretical work on microwave ``ionization'' that show that the present experiments have been in the range of the scaled frequency above 1.14 GHz.
Book ChapterDOI
One-Atom Oscillators for Nonclassical Radiation
F. Diedrich,Joachim Krause,G. Rempe,Marlan O. Scully,Marlan O. Scully,Herbert Walther,Herbert Walther +6 more
TL;DR: In this article, the authors reviewed single atom experiments which have been performed to demonstrate pure quantum features of the radiation field /4,6/ and showed that these properties are pure quantum effects.
