Limits of Quantum Communication Networks; Secret Key Capacity Explored

Limits of Quantum Communication Networks; Secret Key Capacity Explored Establishing the ultimate limits of quantum communication networks At the moment, sensitive data is typically encrypted and then sent across fibre-optic cables and other channels together with the digital “keys” needed to decode the information. However, […]

U.S. Air Force Tests Quantum Communication; Quantum Key Distribution

Air Force Research Laboratory demonstrates world’s first daytime free-space quantum communication enabled by adaptive optics.  The Air Force Research Laboratory (AFRL) Starfire Optical Range (SOR) recently demonstrated quantum communication in daylight under conditions representative of space-to-Earth satellite links. “This is the world’s first such demonstration, […]

Highly Secure, Pan-European Quantum Communication Infrastructure

Highly Secure, Pan-European Quantum Communication Infrastructure.  The European space agency and European Commission agreed to the initial steps in creating a quantum-secure communication network – for Europe.  Excerpt:  It would comprise a series of quantum communication networks, linking institutional users and their critical infrastructures, and […]

U.S. National Science Foundation Soliciting Proposals for Quantum Leap Challenge Institutes

U.S. National Science Foundation Soliciting Proposals for Quantum Leap Challenge Institutes.  The Quantum Leap initiative augments a wide range of NSF investments in quantum information science and engineering.  These efforts, combined with activities supported by other entities, including other government agencies and industry, indicate that […]

Quantum Computing Cloud

Quantum Computing Cloud.  Harvard’s John A. Paulson School of Engineering and Applied Sciences researchers have shifted the frequency of photons using microwaves.  Using a molecule-like photonic system built with lithium niobate on a chip, the team demonstrated that light’s frequency and phase could be controlled by […]
