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.

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中，在这场革命中，我们学会了如何利用这些新规则来建造比经典量子计算设备更强大的量子计算设备。我的项目开发了量子技术，用于对所谓的规范理论进行量子模拟。盖格理论在物理学的许多分支中发挥着核心作用，并描述基本粒子之间的基本相互作用。一个突出的例子是描述夸克和胶子之间相互作用的量子色动力学。由于根本原因，这些理论中的动力过程的计算是非常困难的。这限制了到目前为止可以在经典计算机上进行的模拟，并启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，并将这些新想法推广到实验室中的原理证明实现。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[自然534,516(2016)]，其中实现了一维理论。在提供未知领域的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。我的计划将针对这两个主要研究对象。将量子技术与高能物理联系起来是一个新的、快速发展的领域。我将利用我和我的合作者建立的领先优势，在加拿大这一领域建立强大的研究队伍。今年我从欧洲搬到滑铁卢。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，并利用独特的国际合作组合，这将加强我的HQP的培训。在滑铁卢，对格点规范理论进行量子模拟的第一个实验现在正在进行中。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可见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工作的研究人员(如多伦多的R.Lewis)建立新的联系，为这一研究方向扩大加拿大的网络。Cindy是一个理论程序，用于开发规范理论的量子模拟。它的5年目标是：使非阿贝尔规范理论和超越一维的规范理论能够进行量子模拟。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、早期宇宙物理或中子星内部有关的悬而未决的问题。
