Measurement-device-independent quantum key distribution offers a way of distributing randomness for use in symmetric key cryptography. This work demonstrates the feasibility of using integrated photonic devices for measurement-device-independent quantum key distribution. Using two Indium Phosphide transmitters we have shown the required control for interference between independent devices. The topology of this protocol allows cheap access to the quantum network to users through integrated devices and expensive resources to be shared by the whole network.

Numerically, a theoretical analysis of the noise impact caused by spontaneous Raman scattering, four-wave mixing, and linear channel crosstalk on the measurement-device-independent continuous variable quantum key distribution systems is conducted.The analysis considers symmetry and asymmetry of system paths, as well as possible channel allocation schemes, for a quantum channel located in C-and O-bans.Mathematical models for MDI CV-QKD system and the contributing noises' description are provided.The secure key generation rate is estimated to state features of protocol operation when integrated with existing DWDM systems in the context of its implementation into telecommunication networks.
