2007年5月5日 · We report on a photoionization scheme for controlled loading of 88 Sr + ions into a radio-frequency (rf) ion trap. The two-step doubly-resonant process drives the 88 Sr atom on …

2001年4月1日 · This paper has described the operation of an endcap trap for 88 Sr +. The differences and improvements in the lasers over previous work have been highlighted. A …

2019年11月21日 · We demonstrate key multi-qubit quantum-logic primitives in a dual-species trapped-ion system based on \ ( {}^ {40}\) Ca \ ( {}^ {+}\) and \ ( {}^ {88}\) Sr \ ( {}^ {+}\) ions, …

We describe the loading technique based on two-photon absorption of femtosecond pulses at a wavelength of 431 nm and we compare this technique to electron-bombardment ionization. …

Motivated by the desire to lower the heating rates in planar traps, we design and implement an experiment trapping strontium-88 ions in a knife-edge trap in a helium cryostat. The design …

2011年11月25日 · We report on the construction and characterization of an apparatus for quantum information experiments using 88 Sr + ions. A miniature linear radio-frequency (rf) …

Motivated by the desire to lower the heating rates in planar traps, we design and implement an experiment trapping Sr-88 ions in a knife-edge trap in a helium cryostat. The design …

We describe recent experiments and results which show the effective cancellation of micromotion induced systematic shifts for the 445-THz reference transition in a trapped and laser cooled 88 …

ization scheme for con-trolled loading of 88Sr+ ions into a radio-frequency (rf) ion trap. The two-step doubly-resonant process drives the 88Sr atom on the 5s2 1S0 – 5s5p 1P1 transition at …

A new strontium ion trap of the endcap design was completed last year. This new system has compensation electrodes and access ports in three orthogonal directions to control the ion...
