Research on Entropy, Noise and Chaos appears in PNAS

Our recent experimental study of time-delayed optoelectronic feedback loops incorporating a photon-counting detector has been published in the Proceedings of the National Academy of Science (PNAS). This paper shows a transition from single-photon shot noise to deterministic chaos, and describes
