A Scalable Chip-scale Platform Based on Trapped Ions for Advanced Quantum Systems
Abstract
The overarching goal of the proposed research is the development of a new scalable, high-fidelity,portable, highly stable, and adaptable chip-based platform for advanced quantum systems(AQSs) through integration of leading ion technologies with integrated nanophotonics. Thenanophotonic technology can provide the optical, microwave, and RF fields with precise spatial,spectral, timing, and polarization properties required for next-generation ion-based quantumtechnologies. Combined with recently developed chip-scale ion-trapping technology, uniqueintegrated photonic functionalities (e.g., wavelength multiplexing/demultiplexing, modulation,switching, routing), and efficient beam-shaping and input-output coupling structures by novelmetasurfaces (MSs), the proposed platform enables new scalable quantum chips that facilitate thestudy, design, and optimization of large-scale AQSs for important applications like simulations,sensing, and communications. The proposed platform can provide practical solutions for AQSswhile democratizing quantum systems research, training, and development by considerablyreducing the barrier-to-entry through easily manufacturable and deployable quantum solutions.The proposed chip-scale quantum system is enabled by integration of three important technologies:1) CMOS-compatible integrated photonic material and device platform for enabling low-lossmaterials and functional devices to engineer the temporal and spectral properties of optical beamsfor an intended quantum sensing application, 2) on-chip functional MSs for coupling light out ofthe photonic chip (or back into the chip) with precise amplitude, phase, and polarization profile toshape the optical beam for interaction with trapped ions, and 3) on-chip ion trapping structure andoff-chip state-preparation and cooling beams to enable a complete chip-scale quantum system. Theproposed chip can be extended beyond this project to bring all the laser beams on chip and have asingle chip with integrated ion-traps for quantum applications. Quantum sensor applications willbe demonstrated including a dead-time free atomic frequency reference and a magneticgradiometer.
