Microwave trapped-ion quantum logic gates avoid spontaneous emission as a fundamental source of decoherence. However, microwave two-qubit gates are still slower than laser-induced gates and hence more sensitive to fluctuations and noise of the motional mode frequency.

In our paper we propose and...

We have trapped the first beryllium ions in our cryogenic surface trap. As in our surface traps at room temperature, the ions were loaded by laser ablation from a beryllium wire and subsequent multiphoton ionization. The picture shows a string of three beryllium ions imaged with a CCD camera through...
