Coexisting QKD and Real-Time Encrypted High-Speed Fiber-Optic Communication in Field-Deployed Multi-Core Fibers

Ibrahim Mohamed Ramadan, Giammarco Di Sciullo, Qi Wu +18 more

Quantum key distribution (QKD) coexisting with ultra-high-capacity classical optical signals over the same fiber is widely regarded as a cornerstone of future quantum-safe networks. This approach eliminates the need for dedicated fibers for QKD, significantly reducing infrastructure costs and facilitating large-scale deployment. As a promising foundation for next-generation high-capacity optical networks, multi-core fiber (MCF) opens new possibilities for such coexistence, offering an elegant and spectrum-efficient solution for the integration of quantum and classical channels. Here, we report the first field trial of QKD securely coexisting with bidirectional 106.7 Tb/s full-C-band dense wavelength-division-multiplexed coherent classical transmission over 25.2 km of installed standard-cladding diameter (125 μm) uncoupled-core four-core fiber in L'Aquila, Italy. Despite a classical launch power of 20 dBm per core, a secure key rate of 1.7 kb/s was achieved, using a commercial QKD system. We used the secure keys to achieve real-time encryption of up to 132 Gb/s live traffic within a 400 Gb/s channel, with key refresh intervals as short as 15 seconds. We used hardware encryption, introducing only 52 μs end-to-end latency and jitter below 4 μs compared to the unencrypted case. These results represent a major milestone toward practical, secure, and scalable integration of quantum and classical communication over deployed metropolitan multi-core fiber infrastructure.

Experimental demonstration of reference-frame-independent quantum key distribution with a free-space/fiber integrated channel

Ye Chen, Xiaodong Fan, Tianxiang Zhan +10 more

A global quantum secure network (QSN) based on quantum key distribution (QKD) has emerged as a significant trend since it provides an unconditionally secure way to defeat the threat posed by quantum computers. The nodes, based on ground or mobile platforms, are connected with two different channels, free-space and fiber. In this paper, a qubit-based synchronization reference-frame-independent (RFI) QKD is demonstrated in the field with a free-space/fiber integrated channel, in which the bright classical reference-frame calibration and clock synchronization signals are removed, and the quantum state is directly converted between two different channels without extra coding/decoding operations. It not only reduces the complexity of QKD and QSN but also enhances the practical security (e.g., removing calibration attacks and trusted repeaters). A key rate of 799.2 bps is achieved under 7 km urban free-space and 75 km fiber link. And the long time tests of a continuous 12 h without human intervention also demonstrate the stability of our system under such an integrated channel. Thus, we believe this work opens a way to implement a simple, flexible, and low-cost QSN.

Integration of Quantum Key Distribution and Classical Communications Over Field-Deployed Uncoupled-Core Four-Core Fiber

Qi Wu, Domenico Ribezzo, Giammarco Di Sciullo +8 more

We investigate the integration of quantum key distribution (QKD) into classical optical communication links based on a field-deployed uncoupled-core four-core fiber. We experimentally characterize inter-core spontaneous Raman scattering (IC-SpRS) and evaluate the impact of IC-SpRS and dark counts on QKD performance as the classical traffic load is varied when three cores are used for classical WDM transmission and one for QKD.

Integration of quantum key distribution and high-throughput classical communications in field-deployed multi-core fibers

Qi Wu, Domenico Ribezzo, Giammarco Di Sciullo +23 more

Quantum key distribution (QKD) is a secure communication method for sharing symmetric cryptographic keys based on the principles of quantum physics. Its integration into the fiber-optic network infrastructure is important for ensuring privacy in optical communications. Multi-core fibers (MCFs), the likely building blocks of future high-capacity optical networks, offer new opportunities for such integration. Here, we experimentally demonstrate, for the first time, the coexistence of discrete-variable QKD and high-throughput classical communication in the C-band over a field-deployed MCF with industry standard cladding diameter of 125 μm. Specifically, we demonstrate successful secure-key establishment in one core of a 25.2-km uncoupled-core MCF, while simultaneously loading the remaining three cores with full C-band counter-propagating classical traffic at an aggregate net rate of 110.8 Tb/s. By proposing and experimentally validating an improved analytical model for inter-core spontaneous Raman scattering noise, we find that this configuration is optimal for our deployed MCF link as it is immune to four-wave mixing, that becomes relevant when the quantum and classical signals are propagating in the same direction. Our findings make an important step forward in demonstrating the integration of QKD and classical transmission in uncoupled-core multi-core fibers for next-generation optical communication networks.

Field trial of a finite-key quantum key distribution system in the Florence metropolitan area

Davide Bacco, Ilaria Vagniluca, Beatrice Da Lio +8 more

In-field demonstrations in real-world scenarios boost the development of a rising technology towards its integration in existing infrastructures. Although quantum key distribution (QKD) devices are already adopted outside the laboratories, current field implementations still suffer from high costs and low performances, preventing this emerging technology from a large-scale deployment in telecommunication networks. Here we present a simple, practical and efficient QKD scheme with finite-key analysis, performed over a 21 dB-losses fiber link installed in the metropolitan area of Florence (Italy). Coexistence of quantum and weak classical communication is also demonstrated by transmitting an optical synchronization signal through the same fiber link.
