Technology for On-Chip Qubit Control with Microfabricated Surface Ion Traps

Trapped atomic ions are a leading physical system for quantum information processing. However, scalability and operational fidelity remain limiting technical issues often associated with optical qubit control. One promising approach is to develop on-chip microwave electronic control of ion qubits based on the atomic hyperfine interaction. This project developed expertise and capabilities at Sandia toward on-chip electronic qubit control in a scalable architecture. The project developed a foundation of laboratory capabilities, including trapping the 171 Yb + hyperfine ion qubit and developing an experimental microwave coherent control capability. Additionally, the project investigated the integration of microwave device elements with surface ion traps utilizing Sandia’s state-of-the-art MEMS microfabrication processing. This effort culminated in a device design for a multi-purpose ion trap experimental platform for investigating on-chip microwave qubit control, laying the groundwork for further funded R&D to develop on-chip microwave qubit control in an architecture that is suitable to engineering development.

Ion-Photon Quantum Interface: Entanglement Engineering

Distributed quantum information processing requires a reliable quantum memory and a faithful carrier of quantum information. Trapped ion qubits are the leading realization for quantum information storage, and photonic qubits are the natural choice for the transport of quantum information. The capability to entangle photons with trapped ions in a highly efficient (scalable) fashion is an important achievement. Here, we leverage the active and successful development of micro-fabricated semiconductor ion traps at the Sandia National Laboratory MESA facility, and integrate micro optical components. Compared to current efforts in academic settings combining macro-sized ion traps and optics, a micro device will result in the dramatically increased speed and fidelity of ion-trap based quantum networking protocols. Integrating smaller components will directly allow for a stronger quantum coherent interface between a single trapped ion and a single photon. If successful, this technology could lead to new demonstrations of fundamental physics properties and would open new avenues for scalable quantum networking architectures.
