Abstract

We multiplex a C-band discrete-variable quantum key distribution (DV-QKD), C-band bidirectional service channels for synchronization and key generation, and 39.5-Tb/s Q-band coherent data channels, transmitting them over a 71-km single mode fiber.

11.2 Tb/s Classical Channel Coexistence With DV-QKD Over a 7-Core Multicore Fiber

E. Hugues-Salas, Obada Alia, Rui Wang +4 more

The feasibility of transmitting discrete-variable quantum key distribution channels with carrier-grade classical optical channels over multicore fibers is experimentally explored in terms of achievable quantum bit error rates, secret key rates as well as classical signal bit error rates. A coexistence transmission record of 11.2 Tb/s is achieved for the classical channels simultaneously with a DV-QKD channel over a 1 km-long 7-core multicore fiber. Coexistence over the same multicore fiber core is identified as a dominant factor for the performance of the quantum channel requiring optical bandpass filtering of 17 nm for the quantum channel to avoid the effect of Raman noise. Also, counter-propagation of classical channels and quantum channels probe more tolerance to noise proliferation than co-propagation. In addition, the performance of the quantum channel is maintained when more than three cores are used for the classical channels. Furthermore, by adding a second DV-QKD channel in the multicore fiber, the simultaneous transmission of classical channels as well as the generation of quantum-secured keys of two QKD channels is achieved with an operational range of 10 dB of launched power into the MCF.

Coexistence of 11.2 TB/S carrier-grade classical channels and a DV-QKD channel over a 7-core multicore fibre

E. Hugues-Salas, Qibing Wang, Rui Wang +4 more

We successfully demonstrate coexistence of record-high 11.2 Tb/s (56x200Gb/s) classical channels with a discrete-variable-QKD channel over a multicore fibre. Continuous secret key generation is confirmed together with classical channel performance below the SDFEC limit and a minimum quantum channel spacing of 17nm in the C-band.

Demonstration of 17λ x 10 Gb/s C-Band Classical / DV-QKD Co-Existence Over Hollow-Core Fiber Link

We successfully integrate coherent one-way QKD at 1538 nm in a 7.7 km long hollow-core fiber link with 17 EDFA-boosted C-band data channels from 1540.56 to 1558.17 nm, aggregating a power of 11 dBm. QKD operation proves successful despite the wideband layout of classical channels.
