摘要

Abstract

Trapped ions are a promising modality for quantum systems

with demonstrated utility as the basis for quantum processors and optical clocks. However

traditional trapped-ion systems are implemented using complex free-space optical configurations

whose large size and susceptibility to vibrations and drift inhibit scaling to large numbers of qubits. In recent years

integrated-photonics-based systems have been demonstrated as an avenue to address the challenge of scaling trapped-ion systems while maintaining high fidelities. While these previous demonstrations have implemented both Doppler and resolved-sideband cooling of trapped ions

these cooling techniques are fundamentally limited in efficiency. In contrast

polarization-gradient cooling can enable faster and more power-efficient cooling and

therefore

improved computational efficiencies in trapped-ion systems. While free-space implementations of polarization-gradient cooling have demonstrated advantages over other cooling mechanisms

polarization-gradient cooling has never previously been implemented using integrated photonics. In this paper

we design and experimentally demonstrate key polarization-diverse integrated-photonics devices and utilize them to implement a variety of integrated-photonics-based polarization-gradient-cooling systems

culminating in the first experimental demonstration of polarization-gradient cooling of a trapped ion by an integrated-photonics-based system. By demonstrating polarization-gradient cooling using an integrated-photonics-based system and

in general

opening up the field of polarization-diverse integrated-photonics-based devices and systems for trapped ions

this work facilitates new capabilities for integrated-photonics-based trapped-ion platforms.
