High Speed Time-bin Coding Quantum Key Distribution Terminal

QKD-PHA300 series are quantum communication products launched by QuantumCTek for QKD in the complex channel environment. The product is the world’s first commercial time bin QKD, with multiple patent technologies and a world leading level quantum communication technology. The system is based on BB84 protocol with decoy-state, and employs time-bin coding. The operating frequency of quantum signal transmit or receive module is up to GHz level and can realize long-distance quantum key distribution or high speed quantum key distribution under close distance and small attenuation in special channel environment ( electric aerial optical cable, aerial optical cable bridge, rail buried optical cable, etc.)

QKD-PHA300 series are engine room equipment, mainly used in complex quantum channel environment for secret communication needs. Through model matching use, building security of quantum key distribution network, supplying eavesdropping quantum key cannot be decoded, which has wide application prospect in the military, national security, finance, government, energy and cloud computing, etc.

QKD-PHA300 series products include two types: Signal transmit type (type A) and Signal receive type (type B).
