Frogs and Fireflies illustrating the quantum key distribution scheme BB84 The small quantum cryptography quiltlet, attached to the large Cryptoquilt, illustrates how two parties make a somewhat fanciful use of fireflies, calcite crystals and frogs to implement the quantum key distribution scheme Brassard-Bennett-84 (or BB84), which was the first quantum cryptography protocol; here is aContinue reading “Quiltlet – Mathematical Connections”
