Experimental purification of two-atom entanglement

Author(s)
Rainer Reichle, Dietrich G. Leibfried, Emanuel H. Knill, Joseph W. Britton, Brad R. Blakestad, John D. Jost, C. Langer, R Ozeri, Signe Seidelin, David J. Wineland
Entanglement is one of the most counterintuitive features of quantum mechanics. It is a necessary resource for quantum communication and quantum information...

Fiber-laser frequency combs with subhertz relative linewidths

Author(s)
William C. Swann, John J. McFerran, Ian R. Coddington, Nathan R. Newbury, Ingmar Hartl, Martin E. Fermann, Paul S. Westbrook, Jeffrey W. Nicholson, K Feder, Carston Langrock, Martin M. Fejer
We investigate the comb linewidths of self-referenced, fiber-laser-based frequency combs by measuring the heterodyne beat signal between two independent...

Continuous Light Shift Correction in Modulated CPT clocks

Author(s)
V Shah, Vladislav Gerginov, P Schwindt, Svenja A. Knappe, Leo W. Hollberg, John E. Kitching
We demonstrate a simple technique to significantly improve the long-term frequency stability of atomic clocks based on coherent population trapping (CPT). In...

Michael D. Frenkel, Robert D. Chirico, Vladimir Diky, Chris D. Muzny, Qian Dong, K N. Marsh, John H. Dymond, William A. Wakeham, Stephen E. Stein, Erich Koenigsberger, Anthony R. Goodwin, Joe W. Magee, Michiel Thijssen, William M. Haynes, Suphat Watanasiri, Marco Satyro, Martin Schmidt, Andrew I. Johns, Gary R. Hardin
Thermodynamic data often represent a key resource in the search for new relationships between properties of chemical systems that constitutes the basis of the...
