The effect of atomic response time in the theory of Doppler cooling of trapped ions
H. Janacek, A. M. Steane, D. M. Lucas +1
We describe a simple approach to the problem of incorporating the response time of an atom or ion being Doppler-cooled into the theory of the cooling process. The system being cool…
High-fidelity preparation, gates, memory and readout of a trapped-ion quantum bit
T. P. Harty, D. T. C. Allcock, C. J. Ballance +5
We implement all single-qubit operations with fidelities significantly above the minimum threshold required for fault-tolerant quantum computing, using a trapped-ion qubit stored i…
Background-free detection of trapped ions
N. M. Linke, D. T. C. Allcock, D. J. Szwer +6
We demonstrate a Doppler cooling and detection scheme for ions with low-lying D levels which almost entirely suppresses scattered laser light background, while retaining a high flu…
Heating rate and electrode charging measurements in a scalable, microfabricated, surface-electrode ion trap
D. T. C. Allcock, T. P. Harty, H. A. Janacek +9
We characterise the performance of a surface-electrode ion "chip" trap fabricated using established semiconductor integrated circuit and micro-electro-mechanical-system (MEMS) micr…
