项目摘要
For over a century, scientists have been fascinated, and at times mystified, by quantum mechanics, the theory that governs atoms, molecules and, indeed, all matter at a microscopic level. Central to this theory are two concepts: (1) Wave-particle duality - the idea that particles, such as electrons in an atom, can behave like waves and that light waves can behave like particles, and (2) entanglement - the concept that once two (or more) particles have interacted, they cannot be treated as independent entities no matter how far apart they are. These inherently quantum phenomena are at the heart of a wide range of physical effects, but their role is often extremely difficult to elucidate. For example, in solid materials, where every atom interacts with many other atoms, it is very challenging to predict and understand how the quantum behaviour will manifest itself, and yet it leads to effects, such as high-temperature superconductivity and special forms of magnetism. Our Programme will advance the understanding of these complex quantum systems by studying the behaviour of molecules cooled to very low temperatures where we can isolate their quantum behaviour. In this respect, the use of molecules is crucial. Their rich internal structure means they couple strongly to electric and microwave fields, and interact with each other over a much greater distance compared with atoms. In advancing our understanding of the quantum science of molecules, we will also learn how to harness their properties to build new devices, including sensors of exceptional sensitivity, computers capable of solving previously unsolvable problems, and simulators that can design new materials, magnets and superconductors.To study the quantum science of molecules in a controlled and systematic way, we need to develop the ability to manipulate the quantum properties of individual molecules. The first step towards this goal is to remove the thermal motion that normally hides their quantum behaviour. We have already developed methods to achieve this both using molecules in the solid state and in the gas-phase. In the solid state, we have demonstrated that certain organic dye molecules, when embedded in a suitable solid cooled to cryogenic temperatures, behave as near-ideal two-level quantum systems. Such molecules have the perfect properties to act as interfaces between quantum light and quantum matter - an essential building block of many future quantum devices. We will learn how to exploit these properties to generate single photons on demand, control individual photons, and store quantum information. In the gas phase, we have extended the methods of laser cooling and developed new techniques to cool molecules to within a millionth of a degree above absolute zero. In this quantum regime, it is possible to exert complete control over the internal state and motion of the molecules. With this control we can learn how to couple molecules to microwave and optical waveguides, to trap molecules on chips, to assemble ordered arrays of molecules that replicate the crystalline structure of real materials, and to explore how the interactions between molecules govern the behaviour of the many-particle system. These ambitious goals calls for radical advances, which we will deliver through a set of interconnected experiments intimately linked to state-of-the-art theory. With isolated molecules we will develop the control of single molecules and their coupling to single photons; with small arrays of interacting molecules we will control interactions and entanglement in simple geometries; and with two- and three-dimensional lattices we will understand the complex behaviour of strongly interacting many-particle systems. Through these projects, our Programme will lay the foundations for a broad range of future scientific advances and technological applications based on the quantum control of molecules.
一个多世纪以来,科学家一直着迷,有时被量子力学(控制原子,分子及其实际上都在显微镜水平上都重要的理论)着迷。该理论的核心是两个概念:(1)波颗粒偶性 - 诸如原子中的电子之类的粒子的行为可以像波浪一样行为,而光波可以像颗粒一样行为,而(2)纠缠 - 曾经两个(或更多)粒子相互作用,无法将其视为独立的实体,它们都不会有多远。这些固有的量子现象是广泛的物理效应的核心,但是它们的作用通常很难阐明。例如,在每个原子与许多其他原子相互作用的固体材料中,预测和理解量子行为将如何表现出来非常具有挑战性,但它会导致效果,例如高温超导性和特殊的磁性形式。我们的程序将通过研究冷却到非常低温的分子的行为来提高对这些复杂的量子系统的理解,在那里我们可以隔离它们的量子行为。在这方面,分子的使用至关重要。它们丰富的内部结构意味着它们与电气和微波场相比,与原子相比,彼此相互作用。在促进我们对分子量子科学的理解时,我们还将学习如何利用它们的特性来构建新设备,包括具有特殊敏感性的传感器,能够解决以前无法解决的问题的计算机以及可以设计新材料,磁铁和超导体的模拟器。研究量子的量子和系统的量子,我们需要量子的量子科学。朝着此目标的第一步是去除通常隐藏其量子行为的热运动。我们已经开发了使用固态和气相中的分子实现这一目标的方法。在固态下,我们证明了某些有机染料分子嵌入在适当的固体冷却到低温温度中时,其作用为近乎理想的两级量子系统。这种分子具有完美的特性,可以充当量子光和量子物质之间的接口 - 许多未来量子设备的基本构件。我们将学习如何利用这些属性以按需生成单个光子,控制单个光子并存储量子信息。在气相中,我们扩展了激光冷却的方法,并开发了新技术以冷却分子至超过绝对零的一百万分之一。在这种量子状态下,可以完全控制分子的内部状态和运动。通过这种控制,我们可以学习如何将分子与微波和光学波导,捕获芯片上的分子,以组装有序的分子阵列,以复制真实材料的晶体结构,并探索分子之间的相互作用如何控制许多原理系统的行为。这些雄心勃勃的目标要求进行激进的进步,我们将通过与最新理论密切相关的一系列相互联系的实验来实现。使用分离的分子,我们将发展单分子及其偶联到单光子的控制。使用少量相互作用的分子,我们将控制简单几何形状的相互作用和纠缠。使用二维和三维晶格,我们将了解强烈相互作用的多粒子系统的复杂行为。通过这些项目,我们的计划将根据分子的量子控制为广泛的未来科学进步和技术应用奠定基础。
