Compact Toroidal Ion Trap Design and Optimization
M. J. Madsen, C. H. Gorman
We present the design of a new type of compact toroidal, or "halo", ion trap. Such traps may be useful for mass spectrometry, studying small Coulomb cluster rings, quantum informat…
Efficient Photoionization-Loading of Trapped Cadmium Ions with Ultrafast Pulses
L. Deslauriers, M. Acton, B. B. Blinov +16
Atomic cadmium ions are loaded into radiofrequency ion traps by photoionization of atoms in a cadmium vapor with ultrafast laser pulses. The photoionization is driven through an in…
Ultrafast Coherent Coupling of Atomic Hyperfine and Photon Frequency Qubits
M. J. Madsen, D. L. Moehring, P. Maunz +3
We demonstrate ultrafast coherent coupling between an atomic qubit stored in a single trapped cadmium ion and a photonic qubit represented by two resolved frequencies of a photon.…
Probabilistic Quantum Gates between Remote Atoms through Interference of Optical Frequency Qubits
L. -M. Duan, M. J. Madsen, D. L. Moehring +3
We propose a scheme to perform probabilistic quantum gates on remote trapped atom qubits through interference of optical frequency qubits. The method does not require localization…
Ion Trap in a Semiconductor Chip
D. Stick, W. K. Hensinger, S. Olmschenk +3
The electromagnetic manipulation of isolated atoms has led to many advances in physics, from laser cooling and Bose-Einstein condensation of cold gases to the precise quantum contr…
Broadband laser cooling of trapped atoms with ultrafast pulses
B. B. Blinov, R. N. Kohn, M. J. Madsen +3
We demonstrate broadband laser cooling of atomic ions in an rf trap using ultrafast pulses from a modelocked laser. The temperature of a single ion is measured by observing the siz…
