Quantum optics has the potential to provide highly accurate physical measurements, and to improve the speed and security of communication. The spatial modes of a light field provide a new and interesting basis for these investigations. This fellowship proposes to generate spatially correlated quantum light beams, applying them to spatial positioning applications, such as atomic force microscopy, and to quantum communication protocols. I will experimentally develop general techniques to losslessly combine multiple quantum spatial modes, and demonstrate multi-mode quantum correlations in a light beam. I will investigate the potential of this light to cryptography, densecoding, and atomic force microscopy.

量子光学有可能提供高精度的物理测量，并提高通信的速度和安全性。 光场的空间模式为这些研究提供了一个新的有趣的基础。 该奖学金计划产生空间相关的量子光束，将其应用于空间定位应用，如原子力显微镜和量子通信协议。 我将实验性地发展一般的技术来损耗多个量子空间模式的联合收割机，并演示光束中的多模量子相关性。 我将研究这种光在密码学、加密和原子力显微镜方面的潜力。
