1.25 ERROR MODELS AND QUANTUM ALGORITHMS Quantum errors affect the processing, storage, and transmission of quantum information. In this section we discuss models for errors affecting quantum computations descr
Cryptography and Cryptanalysis 量子计算对传统加密算法构成威胁,同时也推动了新型量子加密技术的发展。 ·量子密钥分发(Quantum Key Distribution, QKD):利用量子力学原理实现安全的密钥交换,提升通信的安全性。 ·量子破解算法(Quantum Cryptanalysis Algorithms):利用量子计算破解传统加密算法,推动密码学的进步。 4. 量子计...
Quantum-safe (sometimes also called “post-quantum”) cryptography is the design and implementation of protocols that are believed to be secure against the added computational capabilities of quantum computers. The two quantum algorithms that cause problems for current cryptography are Grover’s algorithm...

Quantum computers are designed to outperform standard computers by running quantum algorithms. Areas in which quantum algorithms can be applied include cryptography, search and optimisation, simulation of quantum systems and solving large systems of linear equations. Here we briefly survey some known quant...

Optimization of Quantum Algorithms 量子算法的设计和优化是量子计算发展的另一个重要方面。近年来,许多高效的量子算法被提出,如Shor算法和Grover算法,这些算法能够解决经典计算机难以处理的复杂问题。通过优化量子算法,研究人员能够充分发挥量子计算机的优势,提高计算效率和准确性。
英文中的表述是:"Post-quantum Cryptography (PQC)",或者 "Quantum-resistant cryptography"。 1.1.2,为什么需要? 1)量子计算机很强大,但利用其强大算力的前提是:存在能高效解决问题的量子算法,否则量子计算机没什么用,反而因为其高昂的成本带来劣势。数据:5 量子比特的量子计算机造价在千万美元左右。 2)量子计算机...
Post Quantum Cryptography Quantum computers will disrupt existing systems The functioning of the internet and other communication systems relies on secure and efficient cryptographic algorithms. These algorithms allow internet entities to communicate with secrecy, and also to verify the identities of those ...
