Scientists at the Institute for Quantum Computing (IQC) at the University of Waterloo have captured the first images of ultrafast photons that are energy-time entangled. The new technique will have direct applications for quantum cryptography and communication protocols, including the possibility for establishing highly secure communication channels over long distances.
"This technique will allow us to explore all sorts of quantum effects that were inaccessible because the detectors were simply too slow," said Jean-Philippe MacLean, lead author of the study and a PhD candidate in the Department of Physics and Astronomy in the Faculty of Science.
