Testing experimental predictions of quantum gravity.

现代物理学解释了各种令人惊叹的现象，从最小的尺度到最大的尺度，已经彻底改变了世界！激光、半导体和晶体管是我们笔记本电脑、手机和医疗设备的核心。每年，英国和世界各地的国家量子技术计划都在开发新的新型量子技术，这些技术影响着我们的日常生活，也影响着导致新发现的基础物理研究。光的量子状态最近提高了引力波探测器的灵敏度，到目前为止，这种探测器的探测令公众着迷，超导跃迁边缘传感器现在被用于制作高分辨率宇宙图像的天文学实验。尽管现代物理学取得了成功，但仍存在几个深刻而具有挑战性的问题。我们的工作将利用量子技术的最新进展来解决最紧迫的问题之一：量子力学如何与爱因斯坦的相对论相结合？这一系列研究致力于空间和时间的性质。量子计算和引力波探测的最新进展为量子力学和爱因斯坦相对论的一长串成功的实验测试提供了额外的证据。但是，引力如何与量子力学相结合呢？为了寻找这个问题的答案，我们建议研究时空的量子方面。我们将从实验上研究全息原理，即体积的信息内容可以在其边界上编码。我们将利用光的量子态，在更大的桌面规模(5米)上建造两个超灵敏激光干涉仪，以前所未有的灵敏度调查空间不同区域之间可能存在的关联。在现代量子技术的帮助下回答这个具有挑战性的基础物理学问题，有可能为物理学研究开辟新的视野，并达到对我们生活的世界的新理解水平。

Modern physics explains a stunning variety of phenomena from the smallest of scales to the largest and has already revolutionized the world! Lasers, semi-conductors, and transistors are at the core of our laptops, cellphones, and medical equipment. Every year, new novel quantum technologies are being developed within the National Quantum Technology Programme in the UK and throughout the world that impact our everyday life and the fundamental physics research that leads to new discoveries. Quantum states of light have recently improved the sensitivity of gravitational-wave detectors, whose detections to date have enthralled the public, and superconducting transition-edge-sensors are now used in astronomy experiments that make high-resolution images of the universe. Despite the successes of modern physics, several profound and challenging problems remain. Our work will use recent advances in quantum technologies to address one the most pressing questions: how can quantum mechanics be united with Einstein's theory of relativity?This line of research is devoted to the nature of space and time. Recent progress in quantum computing and the detection of gravitational waves have provided additional evidence to the long list of successful experimental tests of quantum mechanics and Einstein's theory of relativity. But how can gravity be united with quantum mechanics? To seek answers that inform this question, we propose to study quantum aspects of space-time. We will experimentally investigate the holographic principle, which states that the information content of a volume can be encoded on its boundary. We will exploit quantum states of light and build two ultra-sensitive laser interferometers on a larger table-top scale of 5m that will investigate possible correlations between different regions of space with unprecedented sensitivity. Answering this challenging question of fundamental physics with the aid of modern quantum technologies has the potential to open new horizons for physics research and to reach a new level of understanding of the world we live in.
