  • Researchers at the University of Rochester and Rochester Institute of Technology recently connected their campuses with an experimental quantum communications network using two optical fibers. In a new paper published in Optica Quantum, scientists describe the Rochester Quantum Network (RoQNET), which uses single photons to transmit information about 11 miles along fiber-optic lines at room temperature using optical wavelengths.

The article from phys.org, published on May 15, 2025, discusses a groundbreaking advancement in quantum communication technology. Researchers have developed a new photon-based system that extends the range of quantum key distribution (QKD) to over 1,000 miles, significantly surpassing previous limitations. This breakthrough, achieved through the use of advanced quantum memories and error correction techniques, promises to revolutionize secure communications by enabling the creation of a global quantum internet. The technology not only enhances the security of data transmission but also paves the way for new applications in fields such as finance, healthcare, and government, where data privacy is paramount.
