Is Quantum Cryptography Provably Secure?

Author(s)
Anastase Nakassis, Joshua Bienfang, P. Johnson, Alan Mink, D. Rogers, Xiao Tang, Carl J. Williams
Quantum cryptography asserts that shared secrets can be established over public channels in such a way that the total information of an eavesdropper can be made...

Spectroscopy of neutral 174Yb in a one-dimensional optical lattice

Author(s)
C Hoyt, Zeb Barber, Christopher W. Oates, A. V. Taichenachev, V. I. Yudin, Leo W. Hollberg
We report spectroscopy of the 1S 0 - 3P 0 clock transition in neutral 174Yb atoms confined to a one- dimensional optical lattice at the ac Stark shift-canceling...

Blackbody radiation shift of the 27Al+ 1S0 - 3P0 transition

Author(s)
Till P. Rosenband, Wayne M. Itano, Piet Schmidt, David Hume, Jeroen Koelemeij, James C. Bergquist, David J. Wineland
The differential polarizability, due to near-infrared light at 1126 nm, of the 27Al + 1S 0 – 3P 0 transition is measured to be {Δ}α = (1.6 ± x 10 -31 m 3, where...

Atom-based stabilization for laser-pumped atomic clocks

Author(s)
Vladislav Gerginov, V Shah, Svenja A. Knappe, Leo W. Hollberg, John E. Kitching
Progress towards simplification and improvement of the long-term stability of chip-scale atomic clocks is presented. The conventional technique of laser optical...
