BB84 quantum key distribution protocol

Target entity: BB84 quantum key distribution protocol
Context triple: [Charles H. Bennett, coInvented, BB84 quantum key distribution protocol]

• A. New Directions in Cryptography
  New Directions in Cryptography is a landmark 1976 paper that introduced the concepts of public-key cryptography and digital signatures, fundamentally reshaping modern cryptography and secure communications.
• B. Quantum Fiber
  Quantum Fiber is a high-speed fiber-optic internet service brand operated by Lumen Technologies, offering residential and business broadband connectivity.
• C. Diffie–Hellman key exchange
  Diffie–Hellman key exchange is a foundational cryptographic protocol that enables two parties to securely establish a shared secret over an insecure communication channel.
• D. Merkle puzzles
  Merkle puzzles are an early cryptographic protocol that introduced the concept of public-key exchange by allowing two parties to establish a shared secret over an insecure channel using computationally asymmetric “puzzle” problems.
• E. Reichenbach synchronization schemes
  Reichenbach synchronization schemes are a family of alternative clock-synchronization conventions in special relativity that generalize Einstein’s method by allowing different, yet empirically equivalent, choices for the one-way speed of light.
• F. None of above. chosen
• G. Unsure - the case is ambiguous/there is not enough information to decide.

Target entity: BB84 quantum key distribution protocol
Target entity description: The BB84 quantum key distribution protocol is a pioneering cryptographic scheme that uses quantum properties of photons to enable two parties to establish a shared secret key with security guaranteed by the laws of quantum mechanics.
