Products and Services

VPIphotonics enables the quantum community to design and develop new QKD technologies and systems efficiently by offering a powerful simulation environment (VPIphotonics Design SuiteTM) that includes various tools and add-ons for photonic component modelling up to optical system level simulation. The VPItoolkitTM QKD provides CV- and DV-QKD modules based on weak-coherent prepare-and-measure protocols, including the corresponding transmitter and receiver modules, parameter estimation and secret key rate calculation. As an add-on to our VPItransmissionMakerTM Optical Systems (part of the VPIphotonics Design SuiteTM), co-existence scenarios with classical channels can be evaluated. Moreover, utilizing the powerful module libraries included in VPItransmissionMakerTM Optical Systems, deteriorating effects such as Raman scattering and different component imperfections like thermal noise, ADC quantisation noise, RIN and phase noise can be investigated. VPIphotonics Design SuiteTM and VPItoolkitTM QKD can serve as a test bed for fibre- and free-space-based QKD system implementations. Build-in automation features and a robust API enable the user to optimise simulation and design parameters efficiently, thus reducing the R&D phase considerably.
