Product Overview
QCRP (Quantum Cryptography Research Platform) is a product dedicated to providing high-speed signal driving and data processing. The QCRP system features a hardware–software co-design, modular control, and a unified operating platform, while supporting a wide range of development environments—including LabVIEW, Python, MATLAB, and C/C++. This allows researchers in quantum cryptography to focus solely on the study of quantum cryptographic protocols, with the QCRP system efficiently handling protocol implementation and data analysis and processing, thereby enabling rapid validation of research objectives. The QCRP-100 model incorporates four core instrument modules for quantum information research: a decoy-state light-source module, an RF amplification module with DC bias, a high-speed clock source, and a high-speed infrared single-photon detector. Each module can be used as a standalone instrument or rapidly integrated into a system configuration, and all modules feature high-precision synchronization. With this platform, users can conveniently conduct research on related QKD systems.
