A short response-time atomic source for trapped ion experiments
Review of Scientific Instruments AIP Publishing 89:5 (2018) 053102
Abstract:
Ion traps are often loaded from atomic beams produced by resistively heated ovens. We demonstrate an atomic oven which has been designed for fast control of the atomic flux density and reproducible construction. We study the limiting time constants of the system and, in tests with 40Ca, show we can reach the desired level of flux in 12 s, with no overshoot. Our results indicate that it may be possible to achieve an even faster response by applying an appropriate one-off heat treatment to the oven before it is used.High-fidelity elementary qubit operations with trapped ions

Abstract:
© OSA 2017. I will describe recent experimental work at Oxford on implementing elementary one- and two-qubit operations with the high fidelities (99.9% or more) required for the implementation of quantum error correction, using trapped-ion “atomic clock“ qubits.Sideband cooling of small ion Coulomb crystals in a Penning trap
