Title:
Photon-to-Spin Interface for Distributed Quantum Sensing with Bullseye Cavity Engineered Semiconductor Quantum Dot Circuit for Enhanced Conversion Efficiency
Agreement Number:
1035735
Agreement Value:
$247,500.00
Agreement Date:
Oct 15, 2025 - Mar 31, 2028
Description:
An efficient photon-to-spin interface is a critical component for Quantum Internetworking for several applications including quantum sensing via distributed entanglement and interfacing “off-chip” remote quantum processors for advanced quantum computing. The Project will develop a photon-to-spin interface that overcomes the current problem of low conversion efficiencies. A promising solution to enhance absorption is to embed the quantum dot circuit in a suspended coaxial ring structure (“Bullseye cavity”) fabricated from a semiconductor quantum well substrate. The Project builds on preliminary work and draws on the Project team expertise in the modeling and fabrication of Bullseye-cavity-engineered semiconductor quantum dot circuits; the understanding of concepts and strategies to enhance performance of the photon-to-spin interface; and deployment of infrastructure to deliver light to quantum dot circuits in the harsh but necessary milli-Kelvin environment.
