论文摘要
开发了一种新版本的量子哈希技术，其中量子哈希被构造为单光子高维状态（QUDITS）的序列。使用单个光子的轨道 - 角动量编码的高维量子散列协议的原理证明实现。结果表明，随着碰撞概率和哈希的解码概率之间的最佳比率，Qudits的数量随着其维度的增加而减少。因此，增加信息载体的尺寸使单个光子的量子散发更有效。
A new version of quantum hashing technique is developed wherein a quantum hash is constructed as a sequence of single-photon high-dimensional states (qudits). A proof-of-principle implementation of the high-dimensional quantum hashing protocol using orbital-angular momentum encoding of single photons is implemented. It is shown that the number of qudits decreases with increase of their dimension for an optimal ratio between collision probability and decoding probability of the hash. Thus, increasing dimension of information carriers makes quantum hashing with single photons more efficient.
