Finite-key analysis for round-robin-differential-phase-shift quantum key distribution

2020 · Optics Express

Since the round-robin-differential-phase-shift (RRDPS) quantum key distribution (QKD) protocol was proposed, it has attracted much attention due to its unique characteristic i.e., it can bind the amount of information leakage without monitoring signal disturbance. Recently, …

Realizing downstream access network using continuous-variable quantum key distribution

2021 · arXiv (Cornell University)

Quantum key distribution (QKD) which enables the secure distribution of symmetric keys between two legitimate parties is of great importance in future network security. Access network that connects multiple end-users with one network backbone can …

Integrated high-performance LDPC decoder for Continuous-Variable Quantum Key Distribution System

2025

The throughput of the error correction decoding is one of the major bottlenecks of high-speed continuous-variable quantum key distribution (CV-QKD) systems and an integrated decoder with Gbps decoding throughput is implemented in this work.

Iterative partition-search variational quantum algorithm for solving the shortest-vector problem

2026 · Physical Review A

The Partition Search Algorithm (PSA) and Iterative Quantum Optimization with an Adaptive Problem (IQOAP) are leading variational quantum algorithms for solving Shortest Vector Problem (SVP). However, each has limitations that restrict its practical impact. IQOAP …
