Reconciliation strategies for continuous variable quantum key distribution

本课题旨在提出一种新的密钥分发方法，称为量子密钥分发，利用光信道的量子态分发安全密钥。密钥分发是数据安全的基础部分，它允许数字密钥在用于保护和共享信息之前在两个或更多方之间安全地交换。预期的结果是专门设计用于长距离量子密钥分发的新型无速率纠错码。量子密钥分发有利于实现超安全通信，因为它避免了弱随机数和量子计算蛮力攻击的脆弱性，这些攻击目前威胁着现有方法保护的数据的安全性。

This project aims to advance a novel key distribution method, called quantum key distribution, which distributes secure keys using the quantum state of optical channels. Key distribution is a foundational part of data security, allowing digital keys to be securely exchanged between two or more parties, before they are used to protect and share information. The expected outcome is new rateless error correction codes designed specifically to implement quantum key distribution over long distances. Quantum key distribution is beneficial for ultra-secure communications as it avoids the vulnerability to weak random numbers and quantum-computing brute force attacks that currently threated the security of data protected by existing methods.
