On the application of radio frequency voltages to ion traps via helical resonators
radio frequency voltages ion traps helical resonators
2011/9/6
Ions confined using a Paul trap require a stable, high voltage and low noise radio frequency (RF) potential. We present a guide for the design and construction of a helical coil resonator for a desire...
A microscopic model of electronic field noise heating in ion traps
A microscopic model electronic field noise heating ion traps
2011/9/13
Motional heating of ions in micro-fabricated traps is one of the open challenges hindering experi-mental realizations of large-scale quantum processing devices. Recently a series of measurements of th...
We fabricate superconducting ion traps with niobium and niobium nitride and trap single 88Sr ions at cryogenic temperatures. The superconducting transition is verified and characterized by measuring t...

We report heating rate measurements in a microfabricated gold-onsapphire surface electrode ion trap with trapping height of approximately 240 m.Using the Doppler recooling method, we characterize the...
Two-dimensional cluster-state preparation with linear ion traps
Two-dimensional cluster-state preparation linear ion traps
2010/4/8
We present schemes to prepare two-dimensional cluster states [H. J. Briegel and R. Raussendorf, Phys. Rev. Lett. {\bf 86}, 910 (2001)] with atomic ions confined in a micro-structured linear ion trap a...
