CINDY: Coherent gauge-invariant dynamics

第一次量子革命教会了我们量子世界的工作原理。现在我们正处于第二次量子革命之中，在这场革命中，我们学习如何利用这些新规则来构建比传统计算设备更强大的量子计算设备。我的项目是为所谓规范理论的量子模拟开发量子技术。规范理论在物理学的许多分支中起着核心作用，它描述了基本粒子之间的基本相互作用。一个突出的例子是量子色动力学，它描述了夸克和胶子之间的相互作用。由于一些根本的原因，在这些理论中计算动力学过程是非常困难的。这限制了迄今为止可以在经典计算机上进行的模拟，并激发了使用量子模拟器的想法。我的计划旨在开发这种新型模拟器的概念，并将这些新颖的想法推广到实验室的原理验证实现中。在我最近的欧洲合作中，我开发的一个硬件适应设计导致了该领域的第一个演示[Nature 534, 516(2016)]，其中一维理论已经实现。在为未知领域提供了第一块踏脚石的同时，它也留下了巨大的挑战，包括具有颜色自由度的理论的量子模拟（如量子色动力学）和超越一个空间维度的实现。我的计划将解决这两个主要的研究目标。将量子技术与高能物理相结合是一个快速发展的新领域。我将利用我和我的合作者建立的领先优势，在加拿大建立一个强大的研究领域。我今年从欧洲搬到了滑铁卢。我的专业知识和世界领先的专家网络将促进知识转移到加拿大，并利用国际合作的独特组合，这将加强我的HQP培训。在滑铁卢，第一个对晶格规范理论进行量子模拟的实验正在进行中。如果我的项目能够及时启动，计划中的理论-实验合作有可能通过高知名度的概念验证实验在这一领域建立领导地位。从长远来看，我还将与加拿大从事晶格规范理论研究的研究人员（例如多伦多的R. Lewis）建立新的联系，扩大加拿大在这一研究方向的网络。辛迪是一个理论程序用于发展规范理论的量子模拟。其5年目标是：实现非阿贝尔规范理论和超一维规范理论的量子模拟。最终的长期愿景是解决无法用数值方法解决的问题，例如与粒子加速器中的重离子碰撞、早期宇宙物理学或中子星内部有关的悬而未决的问题。

The first quantum revolution taught us the working principles of the quantum world. Now we are in the midst of a second quantum revolution, in which we learn how to exploit these new rules to build quantum computing devices that are more powerful than their classical counterparts. My program develops quantum technology for quantum simulations of so-called gauge theories.Gauge theories play a central role in many branches of physics and describe the fundamental interactions between elementary particles. A prominent example is quantum chromodynamics which describes the interaction between quarks and gluons. Due to fundamental reasons, the calculation of dynamical processes within such theories is extremely hard. This limits simulations that can be performed on classical computers to date and inspired the idea to use quantum simulators.My program aims at developing the concepts for this new type of simulator and to promote these novel ideas to proof-of-principle realizations in the lab. In my recent European collaboration, a hardware-adapted design I developed led to the first demonstration in this field [Nature 534, 516 (2016)], where a one-dimensional theory has been realized. While providing a first stepping stone in uncharted territory, it leaves big challenges open, including the quantum simulation of theories with color'- degrees of freedom (as in quantum chromodynamics) and realizations beyond one spatial dimension. My program will address these two major research objectives.Linking quantum technologies with high energy physics is a new and rapidly evolving field. I will leverage the leading edge established by my collaborators and me to establish a strong research line in this area in Canada. I moved from Europe to Waterloo this year. My expertise and network of world leading experts will spur a knowledge transfer to Canada and tap into a unique combination of international collaborations that will enhance the training of my HQP. In Waterloo, the first experiment to perform quantum simulations of lattice gauge theories is now under way. If my program can be started in a timely manner, the planned theoretical-experimental collaboration has the potential to do establish leadership in this area through proof-of-concept experiments with high visibility. In the long run, I will also establish new connections with researchers working on lattice gauge theories in Canada (e.g. with R. Lewis in Toronto) expanding the Canadian network for this research direction.Cindy is a theory program for developing quantum simulations of gauge theories. Its 5-year goals are: to enable quantum simulation of non-Abelian gauge theories and gauge theories beyond 1D. The ultimate long-term vision is to tackle problems that can not be addressed with numerical methods, such as open questions relating to heavy ion collisions in particle accelerators, the physics of the early universe, or the interior of neutron stars.
