Quantum Key Distribution Terminal

QKD-POL40 series are QKD terminals launched by QunatumCTek with fully intellectual property rights. This series of products adopt decoy-state BB84 protocol and polarization coding scheme, can meet the requirements of quantum key distribution in the Metropolitan Area Network.

QKD-POL40 devices are 19-inch 4U standard rackable enclosure, and suitable for the engine room environments, and mainly used in Metropolitan Area Network.

QKD-POL40 can be divided into two types: QKD-POL40A (Transmitting in simplex mode, Type-A), QKD-POL40B (Receiving in simplex mode, Type-B). Type-A and Type-B can be connected together to execute QKD process, and provide quantum secret key, that cannot be decoded or eavesdropped, for the encryption service.

 QKD protocol: BB84 protocol with decoy-state method and polarization coding

 Quantum safe: Against attacks such as photon beam separation attack, light blinding attack and double counting attack

 Channel Adaption: Quantum channel polarization automatic correction

 Hardware implementation: FPGA implementation of QKD protocol & data processing algorithm

 High reliability platform: ATCA carrier-grade architecture, and redundant design with dual power supply, dual fans and etc

 Easy maintained facility: Blade structure and device-level log management

 Convenient expandability: System compatible with third party and provide diverse configuration

 Strict key randomness: Conform to the specification of the State Cryptography Administration

According to each facility's function, this series of products can be divided into two types: QKD-POL40A (Transmitting in simplex mode) and QKD-POL40B (Receiving in simplex mode)
Quantum key distribution in a metropolitan area. The products have been practically applied in thousands of miles of quantum communication networks so far
