Quantum communication and quantum metrology are novel fields where one can go beyond limits given by classical statistical descriptions. In both application areas, light is used as an information carrier, therefore the quantum noise of light plays a crucial role. To extend secure communication with continuous variables to large distances and to increase the sensitivity and precision of quantum sensors, specific quantum processors are required. The goal of the collaboration is to investigate novel concepts for such quantum processors, fulfilling tasks such as noiseless amplification and quantum state filtering. Furthermore, the application in quantum communication and quantum sensing will be explored and experimentally tested in this collaborative project with the Palacky University Olomouc.

量子通信和量子计量学是新的领域，人们可以超越经典统计描述的限制。在这两个应用领域中，光被用作信息载体，因此光的量子噪声起着至关重要的作用。为了将连续变量的安全通信扩展到大距离，并提高量子传感器的灵敏度和精度，需要特定的量子处理器。合作的目标是研究这种量子处理器的新概念，完成无噪声放大和量子态滤波等任务。此外，在与Palacky大学奥洛穆茨的合作项目中，将探索和实验测试量子通信和量子传感的应用。
