LANL/NIST Team Sends Quantum Encryption 'Keys' Over Record Distances

Using an innovative sensor for detecting single photons, the smallest particles of light, scientists from Los Alamos National Laboratory (LANL), the National Institute of Standards and Technology (NIST) and Albion College (Albion, Mich.) have set two significant distance records for distributing “keys” (or codes) for quantum encryption, the most secure method known for protecting the privacy of information.
