Multi-tone RF generation for parallel trapped-ion control*

I present the latest development cycle of our control system designed to address the demands of state-of-the-art quantum computing experiments with trapped ions. Long coherence times and parallel ion control together with optimised gate implementations and low-latency feedback push the limits of what our previous system can do in terms of channel count and multi-frequency generation. Our new platform can efficiently synthesize up to 4 parametrised sine outputs per channel on up to 96 phase-coherent channels and can act as an AWG for parts of the channels.

 

We are in the process of deploying and testing this new system in an experimental setup which is geared towards intermediate-scale quantum computing. It contains a cryogenic segmented-electrode micro-fabricated trap with a multi-core fiber device which is imaged onto the ion string, providing individual ion-control in parallel while an EMCCD camera provides spatially resolved, low-latency readout.
