Capacity and SKR tradeoff in coexisting classical and CV-QKD metropolitan-reach optical links
Cagla Ozkan, Lucas Alves Zischler, Kadir Gumus +3
We demonstrate power-regime-dependent guardband optimization for quantum-classical coexistence in metropolitan DWDM. Quantum channel at band-edge with 100-150 GHz guardbands achiev…
Time-Bin BB84 QKD System Using Indium Phosphide and Silicon Nitride Photonic Integrated Circuits
Denis Fatkhiev, Alexander Grebenchukov, João dos Reis Frazão +3
We demonstrate a dual-chip InP-SiN photonic QKD system with on-chip pulse generation and reconfigurable decoding, implementing time-bin BB84 with finite-key security against cohere…
Compact Continuous-Variable Quantum Key Distribution System Employing Monolithically Integrated Silicon Photonic Transceiver
Denis Fatkhiev, João dos Reis Frazão, Alireza H. Derkani +4
We demonstrate the first CV-QKD system featuring a custom-designed monolithic silicon photonic dual-polarisation transceiver. Leveraging PS-64-QAM, we achieved 1.9 Mbit/s secret ke…
Information Reconciliation for Continuous-Variable Quantum Key Distribution with Using Short Blocklength Error Correction Codes: Proposal and Concerns
Kadir GümüÅ, João dos Reis Frazão, Aaron Albores-Mejia +5
In this paper, we introduce a reconciliation protocol with a two-step error correction scheme that uses a short-blocklength, low-rate code and a long-blocklength, high-rate code. W…
Accurate and Effective Model for Coexistence of Classical and Quantum Signals In Optical Fibers
Lucas Alves Zischler, ÃaÄla Ãzkan, Tristan Vosshenrich +10
The rising interest in quantum-level communication has resulted in proposals for coexistence schemes with classical signals within the same fiber optic channel, where the most rece…
Short Blocklength Error Correction Codes for Continuous-Variable Quantum Key Distribution
Kadir GümüÅ, João dos Reis Frazão, Boris Å koriÄ +4
We introduce a two-step error correction scheme for reconciliation in continuous-variable quantum key distribution systems. Using this scheme, it is possible to use error correctio…
