Robust Two-Qubit Geometric Phase Gates using Amplitude and Frequency Ramping

November 18, 2025
Author(s)
Christina Bowers, Deviprasath Palani, John Barta, Tyler Guglielmo, Stephen Libby, Dietrich Leibfried, Daniel Slichter
We demonstrate a method for generating entanglement between trapped atomic ions based on adiabatically ramped state-dependent forces. By ramping both the amplitude of the state-dependent force and the motional mode frequencies, we realize an entangling

Optical Atomic Clocks

December 1, 2013
Author(s)
Christopher W. Oates, N Poli, P. Gill, G.M. Tino
In the last ten years extraordinary results in time and frequency metrology have been demonstrated. Frequency stabilization techniques for continuous wave lasers and femto-second optical frequency combs have enabled a rapid development of frequency

Anharmonic Phonons and Magnons in BiFeO 3

February 13, 2012
Author(s)
O. Delaire, M. B. Stone, J. Ma, A. Huq, D. Gout, Craig Brown, K. F. Wang, Z. F. Ren
The phonon density of states (DOS) and magnetic excitation spectrum of polycrystalline BiFeO 3 were measured for temperatures 200 less than or equal to}Τ less than or equal to} 750K, using inelastic neutron scattering (INS). Our results indicate that the
