摘要： According to an embodiment, a quantum key distribution device includes a key sharing unit, a correcting unit, a compressor, and a controller. The key sharing unit is configured to generate a shared bit string by using quantum key distribution performed with another quantum key distribution device via a quantum communication channel. The correcting unit is configured to generate a corrected bit string through an error correction process with respect to the shared bit string. The compressor is configured to generate an encryption key through a key compression process with respect to the corrected bit string. The controller is configured to perform a restraining operation in which the total number of bits of encryption keys generated per unit time by the compressor is smaller than the total number of bits of the encryption keys generated per unit time by the compressor in the case of not performing the restraining operation.

摘要： A hardware system and encryption method that generates encryption keys based on quantum mechanical phenomena that can be delivered directly, over public wired and wireless channels, to communicating devices. The encryption strength is derived from physical phenomena and not mathematical complexity and, therefore, is “future proof” against advances in computational power. The present invention allows pre-existing networked devices to communicate securely within a geographically defined “protection zone.”

摘要： An interferometer for controlling the coalescence of a pair of photons, including: an optical source, which generates a first and a second pump pulse coherent with each other and shifted in time by a delay; and a first interferometric stage, which receives the first pump pulse and generates an antisymmetric state with two coalescent photons (1/√{square root over (2)}(|21,02−|01,22)). The interferometer also includes a second interferometric stage, which receives the second pump pulse and generates a symmetric state with two coalescent photons (1/√{square root over (2)}·(|21,02+|01,22)), the first and the second interferometric stages being connected in a manner such that the interferometer outputs a final state equal to a weighted sum of the antisymmetric state and of the symmetric state (1/√{square root over (2)}·(|21,02+|01,22)+eiτ·1/√{square root over (2)}·(|21,02−|01,22)), the weights of the sum being a function of the delay.

摘要： We describe an integrated waveguide device that creates entanglement between a sequence of periodically spaced (in time) photons in a single input and output mode. The device consists of a polarization maintaining integrated waveguide chip containing a number of delay lines, integrated multimode interferometers with the potential for rapid switching, a polarization controller and off chip computer logic and timing. The device is capable of creating a diverse array of outputs such as linear cluster states and ring cluster states in a single output mode.

摘要： Techniques and tools for implementing protocols for secure multi-party communication after quantum key distribution (“QKD”) are described herein. In example implementations, a trusted authority facilitates secure communication between multiple user devices. The trusted authority distributes different quantum keys by QKD under trust relationships with different users. The trusted authority determines combination keys using the quantum keys and makes the combination keys available for distribution (e.g., for non-secret distribution over a public channel). The combination keys facilitate secure communication between two user devices even in the absence of QKD between the two user devices. With the protocols, benefits of QKD are extended to multi-party communication scenarios. In addition, the protocols can retain benefit of QKD even when a trusted authority is offline or a large group seeks to establish secure communication within the group.
摘要翻译：本文描述了在量子密钥分发（“QKD”）之后实现安全多方通信协议的技术和工具。在示例实现中，可信授权有助于多个用户设备之间的安全通信。受信任的机构在与不同用户的信任关系下，通过QKD分配不同的量子密钥。受信任的机构使用量子密钥确定组合密钥，并使组合密钥可用于分发（例如，用于通过公共信道的非秘密分发）。即使在两个用户设备之间没有QKD的情况下，组合键也促进两个用户设备之间的安全通信。通过协议，QKD的优点将扩展到多方通信场景。此外，即使信任的权威机构处于脱机状态，或者大型组织寻求在组内建立安全通信，协议也可以保留QKD的优点。
