Towards a robust system for cryogenic multi-species ion trapping
POSTER
Abstract
The increasing complexity of modern trapped ion quantum information processing experiments requires a stable and adaptable system designed for rapid turnaround. We present a robust cryogenic ion trapping apparatus for complex quantum computing experiments. Modular optical systems are integrated on custom-machined baseplates to stabilize and miniaturize the laser system. Light delivery is enabled by chamber-referenced optical couplers with parabolic mirrors and photonic crystal fibers for simplified alignment and identical focus of multiple wavelengths on an ion chain. We demonstrate trapping, initial quantum control, and high-fidelity state detection of 88Sr+ and present work towards trapping 133Ba+. These two species have visible and infrared transition wavelengths and a favorable atomic structure for quantum information experiments.
