Quantum entanglement is the invisible non-classical link that can exist between objects separated from each other. Although disputed by Einstein, entanglement is now accepted as a fundamental property of the universe. Light sources exist where photons are emitted as entangled pairs, each photon is ill-defined in direction and energy, but measurement of either gives knowledge of both. If one of the beams of photons is used to illuminate an object, then the image is imprinted onto the other / enabling detection by a remote camera. This is called Quantum or Ghost Imaging, an object placed in one location and be imaged at another! This is all thanks to the coherence of quantum mechanics.Making Ghost Imaging work is a technological challenge, one needs to detect the position of individual photons and distinguish these from any and all sources of noise. To date this has only been possible by raster-scanning single detectors backwards and forwards over the image plane / meaning any Ghost image takes a long time to record. In this work we will develop a real-time Ghost Camera giving live Ghost Images.The system will allow us to explore still disputed questions in the interpretation of Quantum Mechanics including the correct angular form of Heisenberg's uncertainty principle; the pioneering of ghost spectroscopy and explore potential applications in covert imaging, surveillance and sensing.To succeed we will develop a new way of using state of the art photon detectors, computer controlled holograms and short pulse laser sources, while verifying the quantum aspects of our work will require a careful theoretical analysis.

量子纠缠是可能存在的对象之间存在的无形的非古典链接。尽管由爱因斯坦（Einstein）提出争议，但纠缠现在被接受为宇宙的基本属性。存在光源在光子发射为纠缠对的地方，每个光子在方向和能量上都不确定，但是测量两者都会有两者的知识。如果使用一个光子的光束来照亮一个物体，则将图像印刷到另一个 /启用镜头的检测到远程相机。这称为量子或幽灵成像，一个放置在一个位置的对象，并在另一个位置成像！这一切都归功于量子力学的连贯性。制造幽灵成像工作是一种技术挑战，需要检测单个光子的位置并将其与任何噪声源区分开。迄今为止，只有通过栅格扫描的单个探测器向后和向前向图像平面 /向前移动 /意味着任何幽灵图像都需要很长的时间才能记录这一可能。在这项工作中，我们将开发一个实时的幽灵摄像机，提供实时的幽灵图像。该系统将使我们能够在解释量子力学的解释中探讨仍然有争议的问题，包括Heisenberg的不确定性原理的正确角度形式；幽灵光谱的开拓性并探索了秘密成像，监视和感应中的潜在应用。为了成功，我们将开发一种使用最先进的光子检测器，计算机控制的全息图和短脉冲激光源的新方法，同时验证我们工作的量子方面需要仔细的理论分析。
