Quantum Key Distribution Demonstration Experimental Setup
Product Overview
The quantum key distribution demonstration experimental setup is a modular teaching system designed based on the BB84 protocol, specifically developed for optical and information security courses in higher vocational colleges. It includes core components such as a polarization-encoded laser source (850 nm), a manual polarization adjuster, and a single-photon detector. The setup supports the construction of simple optical paths to simulate the quantum key distribution process. Students can manually adjust the system to perform operations including key distribution, basis comparison, error correction, and key storage. They can also use the generated keys to demonstrate file encryption and decryption, gaining an intuitive understanding of the principles behind polarization modulation and eavesdropping detection in quantum secure communication. The experimental setup employs conventional optical components—such as beam splitters and polarizers—to reduce costs, while also featuring a design that prevents operational errors, making it ideal for students to quickly grasp the fundamental application scenarios of quantum key distribution.
