YIP Identification and Deterministic Synthesis of Quantum Information Defects (ID-SQUID)
Abstract
The Identification and Deterministic Synthesis of Quantum Information Defects (ID-SQUID) project aims to advance the understanding and synthesis of color centers in hexagonal boron nitride (hBN) as part of efforts to enhance quantum technologies. Unlike traditional 3D quantum emitters which struggle with synthesis uniformity and integration, hBN offers a two-dimensional platform that may support superior color center placement and synthesis specificity, as well as robust quantum functionalities even at room temperature. This project is organized into four main research aims to address fundamental challenges in synthesizing and integrating these quantum systems:1.High-Purity hBN Film Synthesis - Using ultra-high vacuum chemical vapor deposition (UHV-CVD), this aim focuses on growing monolayer to few-layer hBN with low defect densities for subsequent color center creation.2.Defect Identification and Characterization - By employing advanced scanning probe microscopy techniques, this aim will characterize the atomic and electronic structures of intrinsic defects in hBN, which are potential sites for color center formation.3.Deterministic Placement of Color Centers - Utilizing a novel feedback-controlled breakdown method, this aim will attempt precise placement of vacancy color centers within the hBN lattice, enhancing the potential for predictable quantum properties.4.Chemical Modification for Carbon Color Centers - This aim explores the synthesis of carbon-related color centers through controlled chemical reactions and precise atomistic manipulation within hBNstructures. Outcomes include improved color centers for quantum optics, but also programmed interactions between clusters of carboncenters as quantum simulators.Each phase of the project is designed to build on the findings of the previous, supported by a comprehensive management approach that includes regular progress reviews and strategic planning meetings. This enables adaptability to newinsights and continuous alignment with project goals.The potential applications of successfully integrated quantum emitters in hBN are vast, ranging from quantum computing and secure communications to high-resolution quantum sensing, all operable above cryogenic temperatures. This project directly supports the U.S. Navy s strategic objectives for resilient and advanced quantum devices operable in diverse environments, enhancing capabilities in secure communication and precise sensing. This project not only aims to refine the understanding of color center properties but also to develop methodologies for their reliable production, positioning it at the forefront of quantum material research.As the sole principal investigator for this grant, I bring extensive expertise in the synthesis and characterization of two-dimensional materials, with specialized experience in ultra-high vacuum and inert environments essential for quantum technology advancements. At Stanford, I have pioneered new routes to high quality monolayer synthesis, preliminary demonstrations of scanning probe defect patterning, robotic systems for the integration of heterostructures, and the first qPlus cryogenic Photoinduced Force Microscopy (PiFM), underscoring my leadership in applying high-precision techniques to explore new frontiers in quantum materials science.Approved for Public Release.
