Gopinath Group Advances Quantum Sensing With a New Model in Optical Fibers

Research into quantum engineering may provide several significant advancements in optical sensor technology, but optical loss and signal noise have — until recently — held these applications back. In “Realistic model of entanglement-enhanced sensing in optical fibers,“ published in Optics Express earlier this year, the Optics and Photonics Research Group at CU Boulder and their partners predict and demonstrate ...

Dark Fiber Network Finds Missed Aftershocks in Chinese Earthquake

Just days after a 2020 magnitude 5.1 earthquake in Tangshan, China, researchers turned nearly 8 kilometers of unused telecom fiber optic cable, known as “dark fiber,” into a seismic array that detected dozens of aftershocks that were missed by permanent seismic stations. The rapid deployment of the distributed acoustic sensing (DAS) technology doubled the total ...
