Surface trap with dc-tunable ion-electrode distance
Da An, Clemens Matthiesen, Ahmed Abdelrahman +5
We describe the design, fabrication, and operation of a novel surface-electrode Paul trap that produces a radio-frequency-null along the axis perpendicular to the trap surface. Thi…
Local probe of single phonon dynamics in warm ion crystals
Ahmed Abdelrahman, Omid Khosravani, Manuel Gessner +8
The detailed characterization of non-trivial coherence properties of composite quantum systems of increasing size is an indispensable prerequisite for scalable quantum computation,…
Macroscopic quantum information processing using spin coherent states
Tim Byrnes, Daniel Rosseau, Megha Khosla +6
Previously a new scheme of quantum information processing based on spin coherent states of two component Bose-Einstein condensates was proposed (Byrnes {\it et al.} Phys. Rev. A 85…
Dynamic Control of Magnetically Trapped Indirect Excitons by Using External Magnetic Bias
Ahmed M. Abdelrahman, Byoung S. Ham
We demonstrate an on demand spatial control of excitonic magnetic lattices for the potential applications of excitonic-based quantum optical devices. A two dimensional magnetic lat…
Observations of indirect exciton trapping in one- and two-dimensional magnetic lattices
Ahmed M. Abdelrahman, Byoung S. Ham
A simple method to create and control magnetic potentials onto coupled quantum wells is demonstrated for indirect-exciton magnetic confinement. Localized inhomogeneous magnetic pot…
Macroscopic Rabi-Like Oscillations of Ultracold Atoms in an Asymmetrical Two-Dimensional Magnetic Lattice
A. Abdelrahman, M. Vasiliev, K. Alameh
We investigate the existence of the in trapped ultracold quantum degenerate gases, such as Bose-Einstein condensate, in an asymmetrical two-dimensio…
