Description
The optics required for control of trapped-ion quantum systems have posed a major obstacle in scaling experimental systems, despite these qubits’ fundamental qualities. I will discuss recent work on integrated photonic approaches to trapped-ion control [1,2], which may facilitate scaling and simultaneously reduce relevant noise sources even in current small-scale experiments. In addition, tailored optical field profiles achievable with such methods enable atom-light interactions that may allow extensions and improvements to currently used schemes for quantum logic and laser cooling, and in this vein I will discuss recent results from our lab on control of single ion qubits in passively phase stable optical standing waves.
