Integrated Semiconductor Quantum Dots for Photonic Quantum Technology
Over Zoom
Abstract:
Semiconductor quantum dots (QDs) are leading solid-state emitters for integrated quantum photonics, capable of generating on-demand, high-purity single photons as well as entangled photon pairs. However, practical deployment is limited by low extraction efficiency, charge noise, fine structure splitting and fabrication scalability. This talk highlights recent advances in overcoming these bottlenecks using deterministic integration of QDs with electrically contacted circular Bragg grating (CBG) nanostructures to yield bright, electrically tunable quantum light sources with suppressed charge noise. Additionally, this talk will focus on telecom-band QDs compatible with silicon photonics operating at liquid-nitrogen temperatures, alongside marker-free deterministic workflows for scalable, site-controlled device fabrication. These developments provide a practical roadmap toward chip-integrated quantum light sources for long-distance quantum communication.
