Harnessing Dissipation in Hybrid Solid-State Systems for Quantum Sensing and Computing

Abstract

Solid-state spin defects have garnered considerable attention over the past decades as promising platforms for emergent quantum technologies. Due to their high sensitivity for magnetic fields and nanoscale spatial resolution, they have become forefront sensors of condensed matter phenomena that are otherwise elusive to alternative probes. Their long coherence times and optical addressability, which enables control via photonic channels and facilitates seamless integration with other photonic components, have also positioned them as one of the most promising quantum bits alternatives to the leading superconducting technologies. This proposal aims to advance the capabilities of solid-state spin defects for both quantum sensing and quantum information by exploring the many-body quantum dynamics of an ensemble of solid-state spin defects interacting dissipatively with a shared solid-state reservoir. Specifically, using a combination of analytical methods and numerical simulations, the proposed research will develop novel approaches for sensing properties of quantum materials invisible to the current state-of-the-art schemes, which operate solid-state spin defects essentially as single-qubit sensors. This study will also identify solid-state platforms for the generation, manipulation and read-out of many-body entangled states over distances compatible with single-qubit optical addressability, which remains a long-standing challenge. The outcomes of this research program will enhance DoD capabilities in quantum sensing and information processing by providing tunable platforms and innovative protocols for the generation of metrologically useful states and the implementation of direct many-qubit operations. Furthermore, the proposed research will introduce novel quantum sensing approaches to fundamental properties of magnetic and electronic systems, whose potential impact extends across a broad range of DoD research divisions.
