High-Spin States in a One-Dimensional Carbon Host for Qudits.
Abstract
Qudits are multilevel quantum bits that can extend the Hilbert space of a multielectron spin system. Compared to their binary counterparts, qudits may offer new possibilities to noise-resilient quantum cryptography, improved quantum metrology, and the building of dense quantum architectures. These technological advantages encompassed by spin qudits have promoted their research and development in the field. In this proposed project, we aim to explore an original approach for creating designer quantum defects in a one-dimensional carbon host that would support long-lived, optically addressable high spin states. Specifically, we will leverage the design freedom we have over the atomic structures of the quantum defects to investigate major factors that govern the defects ground and excited state spin manifolds, as well as their spin coherence properties, with the goal of optimizing the defect structures for optically addressable high-spin states. The quantum defects proposed here have the potential to play an important role in near-future scalable quantum devices. Moreover, the general strategy proposed here is rather platform independent and may inspire innovative solutions to other quantum building blocks.
