IdealPhotonics' quantum encryption kit is a teaching and experimental system based on the principle of quantum key distribution (QKD). It intuitively demonstrates the unconditionally secure quantum communication process through single-photon encoding and measurement modules (such as BB84 protocol components), covering the entire chain from preparation, transmission, and detection.Physical layer information security and teaching verifiability are achieved through the hardware implementation of the quantum no-cloning theorem, transforming abstract cryptographic theory into observable eavesdropping detection experiments, while also being compatible with classical encryption comparison teaching.
