Photonics Focus vol. 6 issue 1

January/February 2025 | Vol. 6 | Issue 1

This issue of Photonics Focus explores the weird, wonderful, and sometimes worrisome realm of quantum technologies.  One story highlights the background and current status of the quantum space race as nation's vie for national security supremacy via an unhackable space-based quantum internet. Another feature details the search for a perfect single-photon source, which will be key to enabling many quantum technologies within grasp. A third story looks at a panoply of sensors at work today, their unique features enabled by quantum technologies.
