Capturing a single photon of light: Harnessing quantum’s ‘noise problem’The research, led by Raytheon Intelligence & Space, has potential applications for sensors, communications and quantum computers. As an example, it was one of the first nodes in the ARPANET, the precursor of the internet funded by the Defense Advanced Research Projects Agency, or DARPA. “We’ve filled a technological void with the first Josephson junction to detect a single photon,” said Fong. “However, we can utilize this same phenomenon to detect a single photon, allowing the traffic to continue to speed along. Scientists at Raytheon BBN work in broad-reaching portfolios, while quantum engineering and computing continues to show promise for next-generation capabilities. The team has published its work, which centers on the use of a component called a Josephson junction, in the academic journal Science. The interruption could destroy the data in quantum computing applications,” Fong said.
