Anomalous heating of trapped atomic ions is a major obstacle to their use as quantum bits in scalable quantum computers. The physical origin of this electric field noise is not fully understood, but experimental evidence suggests that it emanates from the

A 750 mW, continuous-wave, solid-state laser source at 313 nm for cooling and manipulating trapped 9Be+ ions

We present a solid-state laser system that generates 750 mW of continuous-wave, single frequency, output at 313 nm. Sum-frequency generation with fiber lasers at 1550 nm and 1051 nm produces up to 2 W at 626 nm. This visible light is then converted to UV

Single-qubit-gate error below 10 -4 in a trapped ion

In theory, quantum computers can solve certain problems much more efficiently than classical computers [1]. This has motivated experimental efforts to construct and verify devices that manipulate quantum bits (qubits) in a variety of physical systems [2]

Coupled quantized mechanical oscillators

March 10, 2011
Author(s)
Kenton R. Brown, Christian Ospelkaus, Yves Colombe, Andrew C. Wilson, Dietrich G. Leibfried, David J. Wineland
The harmonic oscillator is one of the simplest physical systems but also one of the most fundamental. It is ubiquitous in nature, often serving as an approximation for a more complicated system or as a building block for larger models. Realizations of
