A universal geometric π-phase gate between two beryllium ion-qubits is demonstrated, based on coherent displacements induced by an optical dipole force, which makes it attractive for a multiplexed trap architecture that would enable scaling to large numbers of ions.

This work investigates the dynamics of single and multiple ions during transport between and separation into spatially distinct locations in a multizone linear Paul trap for scalable quantum information processing with trapped ions.
Microfabricated surface-electrode ion trap for scalable quantum information processing.

Measurements of ion recooling after cooling is temporarily suspended yield a heating rate of approximately 5 motional quanta per millisecond for a trap frequency of 2.83 MHz, sufficiently low to be useful for QIP.
100-fold reduction of electric-field noise in an ion trap cleaned with in situ argon-ion-beam bombardment.

This study investigates the role of adsorbates on the electrodes by identifying contaminant overlayers, implementing an in situ argon-ion-beam cleaning treatment, and measuring ion heating rates before and after treating the trap electrodes' surfaces, finding a 100-fold reduction in heating rate after treatment.
