This article marks the first open‑air transmission of photonic qubits between Brookhaven and Stony Brook, demonstrating that quantum information can be sent “wirelessly” without a dedicated fiber link. The result dovetails with recent satellite‑based QKD experiments by showing that ground‑to‑ground free‑space links are viable building blocks for a hybrid quantum internet that stitches together fiber, satellite and airborne nodes. While atmospheric turbulence and loss still limit range, the work proves a key step toward flexible, scalable quantum networks that could eventually support secure communications across cities and remote locations.

Summary
Insider Brief PRESS RELEASE — Researchers at the U.S. Department of Energy’s (DOE) Brookhaven National Laboratory and the State University of New York at Stony Brook (Stony Brook University) have successfully transmitted light particles containing quantum information through open air between the two institutions. This is the first demonstration of its kind in the United […]
