Single Photon Detector Conquers the Dark Side

Researchers from the National Institute of Standards and Technology (NIST) and Boston University have demonstrated a detector that counts single pulses of light, while simultaneously reducing false or “dark counts” to virtually zero. Quantum communications and cryptography is a codemaker’s Holy Grail. The idea is to use a rapid series of light pulses (photons) in one of two different states to transmit information in an unbreakable code.
