In CV-QKD the trusted-receiver assumption allows for a significant improvement in terms of key rate and achievable transmission distance. Moreover, as we demonstrate, sometimes detection noise can even be beneficial for the key rate.
At OFC 2019 in San Diego we posed the question how a practical integration of quantum channels into passive optical access networks could look like. To do so, we should first pay attention to the FSAN roadmap. 5G is on the brink of being rolled out together with its optical fronthauling over cloud-radio limited reach of ~20 km, while access standards incorporate wavelength stacking towards 4 lanes of 10 Gb/s. The good news is: NG-PON2 with its WDM overlay is spectrally allocated at the C- and L-bands. This blanks out the O-band, and if we expect fiber deployment to dismiss legacy solutions, there is really much unoccupied space down there at 1310 nm.
A cost-effective QKD transmitter is evaluated in a 16km reach, 2:16-split PON and yields 5.10-7secure bits/pulse. Co-existence with 20 down-and 1 upstream channel is possible at low QBER degradation of 0.93% and 1.1%.
First demonstration of quantum-secured end-to-end VNS composition through dynamic chaining of VNFs from multiple-domains. We rely on a novel quantum-switched flexi-grid WDM network and q-ROADM for inter-connectivity and on-demand selection of transport functions for quality-of-service.
The second quantum revolution is imminent and quantum communications is one of the main reasons since it has been identified as information-theoretical secure for data transmission. However, to achieve quantum communication networks, available compact and highperformance modules are needed together with deployed experimental testbeds for the evaluation of these modules with real application scenarios. …
Communication and dissemination of project results is of major importance for the project participants. The goal of the project partners is to raise awareness, inform and engage the target audience and promote the project’s results. For these reasons we published a press release at the beginning of the project and designed the project’s communication kit. …
In this document we present the UNIQORN website and the Twitter and LinkedIn accounts. The UNIQORN website and social media accounts have been set up in the first project month aiming at raising awareness about the project, informing and engaging with the target audience and promoting the project’s outputs and results. …
This deliverable presents the UNIQORN factsheet and the project’s overview presentation. The project factsheet contains information about the project idea and the project participants and will be distributed in various scientific and industry events where the project partners are planning to participate. …
