Stability thresholds and calculation techniques for fast entangling gates on trapped ions

Bentley, C D B; Taylor, R L; Carvalho, A R R; Hope, J J

Description

Fast entangling gates have been proposed for trapped ions that are orders of magnitude faster than current implementations. We present here a detailed analysis of the challenges involved in performing a successful fast gate. We show that the RWA is a stable approximation with respect to pulse numbers: the timescale on which we can neglect terms rotating at the atomic frequency is negligibly affected by the number of pulses in the fast gate. In contrast, we show that the laser pulse...[Show more]
