Nanoscale Quantum Emitters Integrated by All-Fiber Optofluids
Abstract
Future quantum networks and quantum communication systems require efficient integration of quantum emitters with optical fibers. However, state-of-the-art quantum emitters are based on either trapped atoms in a vacuum or artificial atoms inside semiconductors, posing a grand challenge in fiber optic integration. In this project, we propose to develop a fiber-integrated quantum photonic platform that can efficiently couple photons from nano-scale quantum emitters to guided modes in an optical fiber. The project entails three primary objectives, including the development of (1) fiber-integrated quantum light source with unprecedented coupling efficiency, (2) fiber-integrated spin-photon quantum interface, and (3) entanglement generation and distribution over a fiber-based optical network. To achieve these goals, the research team will develop new techniques for deterministic loading of single quantum emitters into optical fibers, dynamic control of quantum emitters in optical fibers, triggered emission of photons in an optical fiber, and coherent interactions between emitters and photons in a fiber. Low-loss fiber-based optical devices such as beamsplitters, phase shifters, and spectral filters will also be developed for efficient processing of optical photons in optical fibers. The proposed fiber-integrated platform will enable scalable quantum photonic devices and quantum repeaters that are compatible with fiber-based quantum communication systems, which will find important applications in secure quantum communication, quantum networks, distributed quantum computing, and entanglement enhanced quantum metrology
