Dispersive Hong-Ou-Mandel Interference with Finite Coincidence Windows
T. J. Walstra, A. J. Hasenack, D. J. de Ruiter +3
Hong-Ou-Mandel (HOM) interference is a fundamental tool for assessing photon indistinguishability in quantum information processing. While the effect of chromatic dispersion on HOM…
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…
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…
Early Termination of Low-Density Parity-Check Codes for Continuous-Variable Quantum Key Distribution
Kadir GümüÅ, João dos Reis Frazão, Vincent van Vliet +4
We analyse the impact of log a-posteriori early termination on the decoding throughput of reconciliation for continuous-variable quantum key distribution. Increases in decoded secr…
Rate-adaptive Reconciliation for Experimental Continuous-variable Quantum Key Distribution with Discrete Modulation over a Free-space Optical Link
Kadir GümüÅ, João dos Reis Frazão, Vincent van Vliet +8
Continuous-variable quantum key distribution (CV-QKD) has been proposed as a method for securely exchanging keys to protect against the security concerns caused by potential advanc…
