Quantum Gates on Individually-Addressed Atomic Qubits Subject to Noisy Transverse Motion

Autor: Cetina, M., Egan, L. N., Noel, C. A., Goldman, M. L., Risinger, A. R., Zhu, D., Biswas, D., Monroe, C.

Individual trapped atomic qubits represent one of the most promising technologies to scale quantum computers, owing to their negligible idle errors and the ability to implement a full set of reconfigurable gate operations via focused optical fields.

Ultrafast many-body interferometry of impurities coupled to a Fermi sea

Autor: Cetina, M., Jag, M., Lous, R. S., Fritsche, I., Walraven, J. T. M., Grimm, R., Levinsen, J., Parish, M. M., Schmidt, R., Knap, M., Demler, E.

The fastest possible collective response of a quantum many-body system is related to its excitations at the highest possible energy. In condensed-matter systems, the corresponding timescale is typically set by the Fermi energy. Taking advantage of fa

Point sets that minimize $(\le k)$-edges, 3-decomposable drawings, and the rectilinear crossing number of $K_{30}$

Autor: Cetina, M., Hernández-Vélez, C., Leaños, J., Villalobos, C.

There are two properties shared by all known crossing-minimizing geometric drawings of $K_n$, for $n$ a multiple of 3. First, the underlying $n$-point set of these drawings has exactly $3\binom{k+2}{2}$ $(\le k)$-edges, for all $0\le k < n/3$. Second

3--symmetric and 3--decomposable drawings of $K_n$ (extended version)

Autor: Ábrego, B., Cetina, M., Fernández--Merchant, S., Leaños, J., Salazar, G.

Even the most superficial glance at the vast majority of crossing-minimal geometric drawings of $K_n$ reveals two hard-to-miss features. First, all such drawings appear to be 3-fold symmetric (or simply {\em 3-symmetric}) . And second, they all are {

Laser cooling of trapped ytterbium ions with an ultraviolet diode laser

Autor: Kielpinski, D., Cetina, M., Cox, J. A., Kaertner, F. X.

Publikováno v: Opt. Lett. 31, 757 (2006)

We demonstrate an ultraviolet diode laser system for cooling of trapped ytterbium ions. The laser power and linewidth are comparable to previous systems based on resonant frequency doubling, but the system is simpler, more robust, and less expensive.
