摘要： A quantum key distribution protocol is provided that reduces the maximum value of the leaked information amount over the same distance when an adversary makes a photon number splitting attack more than the reduction by the BB84 protocol and the SARG protocol, by making use of the advantages of the BB84 protocol and the SARG protocol. By properly proportioning the existing BB84 protocol and the SARG protocol in accordance with the rate determined by the communication distance between the sender and the receiver of the coherent light, a protocol that is more robust against photon number splitting attack than the known existing protocols can be realized, and long distance quantum key distribution, which was not possible until now, becomes possible.
摘要翻译：提供了一种量子密钥分发协议，当对手进行比BB84协议和SARG协议的减少更多的光子数分裂攻击时，通过利用以下优点，减少了相同距离上的泄漏信息量的最大值： BB84协议和SARG协议。通过根据相干光发射机和接收机之间的通信距离确定的速率，将现有的BB84协议和SARG协议适当地配比，可以比已知的现有协议更能抵御光子数分裂攻击的协议实现和长距离的量子密钥分发是迄今为止无法实现的。

摘要： Provided is a two-dimensional code structured in such a way that the identification function for each of multiple components constituting the two-dimensional code, which have been concatenated and encoded in the form of structured append, has been enhanced. In a set of multiple two-dimensional codes that have been encoded in the form of structured append, wherein the two-dimensional code comprises an information area, an illustration area, and a parity area, each two-dimensional code which is a component of the set of multiple two-dimensional codes is a two-dimensional code having the same graphical illustration drawn in the illustration area.
