量子密码的技术基础要认识量子密码,首先要了解什么是量子、量子计算机和量子通信。量子和量子信息学微观世界的某些物理量是不能连续变化的,只能取某些分立值,相邻两个分立值之差称为该物理量的一个量子。自然界的这种不连续的量子性质,是德国物理学家普朗克于1900年发现的。在此基础上建立了量子力学。由于量子特性在信息领域中有着独特的功能,在提高运算速度、确保信息安全、增大信息容量和提高检测精度等方面可能突破经典信息系统的极限,量子力学首先在信息科学中得到应用,一门新的学科分支——量子信息学也应运而
The Quantum Cryptography Basics To understand quantum cryptography, you first need to understand what is quantum, quantum computer, and quantum communication. Quantum and Quantum Informatics Some of the physical quantities in the microscopic world are not continuously variable. They can only take some discrete values. The difference between two adjacent discrete values is called a quantum of the physical quantity. This discontinuous quantum nature of nature was discovered by the German physicist Planck in 1900. On this basis, established quantum mechanics. Quantum mechanics is first applied in information science due to its unique function in the field of information. It may break the limit of classical information system in terms of increasing computing speed, ensuring information security, increasing information capacity and improving detection accuracy. The new discipline branch - Quantum Informatics should come
