本发明涉及一种基于实时熵估计的自适应量子随机数生成方法，属于量子随机数生成技术领域。现有集成化量子随机数发生器因物理熵源非平稳特性，导致熵率动态漂移，固定后处理参数难以同时保证随机性安全与生成效率。本发明通过实时统计原始随机比特流的状态转移概率并引入置信区间校正计算最小熵，据此动态调整输入位宽，重构Toeplitz矩阵进行随机性提取，实现压缩比的自适应调节。该方法在熵源质量下降时增大压缩比以确保输出随机数安全性，在熵源质量提升时减小压缩比以提高生成效率，从而在保持集成化和低成本前提下，实现随机性安全与生成效率的动态平衡。

0000 A method for secure quantum communication includes generating a photon. The method includes modulating at least two quantum state dimensions selected from the group consisting of orbital angular momentum (OAM), polarization, and phase of the photon to form a composite quantum state. The method includes directing the photon to an emission point on a structure having a defined spatial coordinate corresponding to classical data. The method includes emitting the photon from the emission point into a quantum channel. The composite quantum state and emission-point spatial coordinate jointly encode secure quantum information for transmission.

0000 A system for implementing security measures to a data packet is disclosed. The system assigns each computing device with a respective encryption key. A first computing device encrypts the data packet with a first encryption key upon creation and/or before transmission. The first computing device encodes the data packet with a quantum encryption key and communicates the encoded data packet to a second computing device. The second computing device determines whether the data packet is received without being intercepted. In response to determining that the data packet is received without being intercepted, the second computing device decrypts the data packet.

A system includes a quantum memory configured to store a first quantum cryptographic key and a quantum processor operably coupled to the quantum memory and configured to generate pairs of entangled quantum bits (QuBits). The pairs of entangled QuBits include the first quantum cryptographic key. The quantum processor is further configured to determine, based on one Qubit of each pair of entangled QuBits, a first set of measurements, transmit the pairs of entangled QuBits to the quantum computing device, and in response to transmitting the pairs of entangled QuBits, receive, from the quantum computing device, a second set of measurements of each pair of entangled QuBits. The quantum processor is further configured to identify, based on a comparison of the first set of measurements and the second set of measurements, a second quantum cryptographic key. The second quantum cryptographic key is between the system and the quantum computing device.

In a method for supporting secure data transmission between a first device and a second device, the first device and a trusted authority, TA, possess a first-device pre-shared key, PSK, and the second device and the TA possess a second-device PSK. The TA generates parity information between the first-device PSK and the second-device PSK. The TA communicates the parity information to at least one of the first device and the second device.
