Researchers from the University of Bristol’s Quantum Engineering Technology Labs (QET Labs) and Université Côte d‘Azur have made a miniaturised light detector to measure quantum features of light in more detail than ever before. The device, made from two silicon chips working together, was used to measure the unique properties of “squeezed” quantum light at record high speeds. Harnessing unique properties of quantum physics promises novel routes to outperform the current state-of-the-art in computing, communication and measurement. Silicon photonics – where light is used as ...
