TL;DR: 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.

TL;DR: In this article, the authors demonstrate a universal geometric pi-phase gate between two beryllium ion-qubits, based on coherent displacements induced by an optical dipole force.

TL;DR: In this article, the authors describe a randomized benchmarking method that yields estimates of the computationally relevant errors without relying on accurate state preparation and measurement, since it involves long sequences of randomly chosen gates, and also verifies that error behavior is stable when used in long computations.

TL;DR: 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.
