项目摘要

Quantum Technologies promise to harness the power of quantum mechanics to deliver a new generation of devices whose performance surpasses what is possible with conventional technology. We can expect Quantum Technologies to deliver more powerful methods of computation, completely secure communication, enhanced metrology and sensors with unparalleled sensitivity. Accordingly, the development of Quantum Technologies has attracted substantial investments from national funding agencies worldwide, including in the UK and USA, as well as significant private investment in numerous start-up companies.Many Quantum Technology platforms are being developed, including trapped ions, ultracold atoms, superconducting devices and photons, each with their own strengths and weaknesses. Compared to these more established technologies, ultracold molecules are new to the arena. And yet molecules have many advantages stemming from their rich internal structure of vibration and rotation, long-range dipole-dipole interactions and strong coupling to applied electric and microwave fields.The goal of this proposal is to establish an international collaboration focused on overcoming the scientific and technical challenges that lie between our current experimental platforms and the realisation of molecular Quantum Technologies.Our collaboration involves researchers from Durham University, Imperial College, Oxford University, Harvard University and JILA at the University of Colorado. Our team consists of 10 world-leading investigators, all of whom are embedded in internationally recognised centres of excellence for atomic, molecular and optical physics research. Each investigator brings complementary expertise spanning the experimental and theoretical methods needed to realise our vision. Over the last decade, we have all individually contributed to the transformation of the field of ultracold molecules. We have learned how to produce a wide range of molecular species at ultracold temperatures - the key first step necessary to reveal and access the quantum behaviour of molecules. Subsequently, we have learned to trap, manipulate and control individual molecules at the quantum level. With our molecules now under control and a wave of second-generation experimental platforms coming online, we are on the cusp of a new era for ultracold molecule research. Now is therefore the perfect time for us to join forces and coordinate our research effort in this flourishing field towards Quantum Technology.Our specific research programme is organised around three major, inter-related goals. Firstly, we will learn to control molecule-molecule and atom-molecule collisions and interactions, enabling us to further cool our molecules deep into the quantum regime. Secondly, with our control of molecule-molecule interactions, we will create many-body quantum states of molecules in optical lattices suitable for quantum simulation of systems that are difficult to model on a classical device. Finally, we will learn how to engineer high-fidelity quantum gates between molecules held in optical tweezers - the essential building block of a molecule-based quantum computer.Successful delivery of these ambitious research goals will establish ultracold molecules as a competitive Quantum Technology and will enhance the UK's leadership in this strategically important area.

量子技术有望利用量子力学的力量提供新一代的设备，其性能超过了传统技术的可能性。我们可以预期，量子技术能够提供更强大的计算方法，完全安全的通信，增强的计量和传感器，并具有无与伦比的灵敏度。因此，量子技术的发展吸引了全球国家资助机构的大量投资，包括英国和美国，以及对众多初创公司的大量私人投资。正在开发许多量子技术平台，包括陷阱离子，超速原子，超导设备和光子，每个量子都具有自己的优势和弱点。与这些更具成熟的技术相比，超冷分子是竞技场的新手。然而，分子具有许多优势，这是由于它们丰富的振动和旋转内部结构，远距离偶极 - 偶极相互作用以及与应用电力和微波领域的强大耦合。该提议的目标是建立一个集中于克服我们当前的实验平台和实验量的科学挑战的国际合作群体，这些挑战是从我们当前的实验平台和帝国量化的大学中涉及的帝国量化，这些挑战涉及众所周知的帝国量化，并涉及帝国量化的大学。牛津大学，哈佛大学和科罗拉多大学的吉拉。我们的团队由10位世界领先的调查员组成，所有研究人员都嵌入了国际公认的原子，分子和光学物理学研究中的卓越中心。每个研究者都带来了实现我们愿景所需的实验和理论方法的补充专业知识。在过去的十年中，我们都分别促进了超速分子领域的转化。我们学会了如何在超低温度下产生各种分子物种 - 揭示和访问分子量子行为所需的关键第一步。随后，我们学会了在量子水平上捕获，操纵和控制单个分子。随着我们的分子现在受到控制，第二代实验平台的浪潮即将到来，我们正处于超速分子研究的新时代。因此，现在是我们联合起来并协调我们在这个繁荣领域的量子技术的研究工作的最佳时机。我们的特定研究计划围绕三个主要的，相互关联的目标组织。首先，我们将学会控制分子 - 分子和原子 - 分子碰撞和相互作用，从而使我们能够进一步冷却分子深入量子状态。其次，通过控制分子 - 分子相互作用，我们将在适用于难以在经典设备上建模的系统量子模拟的光学晶格中创建多体量子态。最后，我们将学习如何在光学镊子中持有的分子之间进行高保真量子门 - 基于分子的量子计算机的基本构建块。这些雄心勃勃的研究目标的成功传递将建立超声分子作为竞争性量子技术，并将增强英国在这一战略性重要领域的领导。
