Optical-Fiber based Single-Photon Light Source at Room Temperature for Next-Generation Quantum Processing

Single-photon emitters quantum mechanically connect quantum bits (or qubits) between nodes in quantum networks. They are typically made by embedding rare-earth elements in optical fibers at extremely low temperatures. Now, researchers from Japan, led by Associate Professor Kaoru Sanaka from Tokyo University of Science, have developed an ytterbium-doped optical fiber at room temperature. By avoiding…
