Quantum computers, a grand challenge in the rapidly expanding field of experimental quantum information processing, are perhaps decades away. Quantum simulators - well-controlled experimental quantum systems to simulate specific quantum models are practical with current technologies. They can be useful in the near future to solve problems of quantum physics and chemistry, which are intractable on super-computers. Quantum simulators have indeed been built in recent times with several hardware platforms, such as trapped-ions, ultra-cold neutral atoms, and some solid state systems. They have been used to study models of quantum many-particle systems, such as interacting electrons tunneling on a lattice in a condensed matter system, or models of quantum magnetism. However, current quantum simulators either have too few qubits to be practically useful, or are restricted to solve only a few specific problems, such as a specific quantum model on a fixed geometry. My research program concerns both of these problems and has the ultimate goal of building a quantum simulator with over a hundred trapped-ion qubits that are programmable at the level of individual qubits and interactions between them. In the next 5 years, our research will be carried out in two parallel efforts by graduate students, postdoctoral fellows, and undergraduate researchers. The first effort aims to realize arbitrarily programmable qubit-qubit interactions in about ten Yb+ ion qubits. This will enable the simulator to go beyond the physical geometry of the ion chain and solve quantum dynamics on re-configurable lattice geometry. We will develop a novel holographic optical method using Digital Light Projection (DLP) technology to individually address single ions. The second effort aims to increase the system size to many dozens of qubits. For this, we will develop a dual species quantum simulator (Yb+/Ba+), with Yb+ as the qubits and Ba+ as coolants to enhance quantum coherence. In the future, the two research efforts will be combined to realize a large quantum system that is arbitrarily programmable.HQPs will be trained in a broad range of topics, including safe operations of high power lasers, optics, electronics, DLP technology, ultra-high vacuum, ion traps, spectroscopy, quantum information sciences, quantum many-body physics, and atomic physics. These trainings will prepare HQPs well for future career options including academia and industry. This research program will contribute new fundamental and technical advances in the field of quantum information, and will further position Canada as a world leader in quantum information research, as there are only a handful of advanced quantum simulators in the world. The talent pool and expertise created will boost Canada's economy by contributing to the rapidly growing field of quantum technologies, which promise to fundamentally change our economy and society in near future.

量子计算机是实验量子信息处理的迅速扩展领域的巨大挑战，可能已经数十年了。量子模拟器 - 模拟特定量子模型的控制良好的实验量子系统对当前技术是实​​用的。它们在不久的将来可以解决量子物理和化学问题的问题，这些问题在超级计算机上很棘手。量子模拟器确实在最近的几个硬件平台，例如被困的离子，超冷中性原子和一些固态系统。它们已用于研究量子多粒子系统的模型，例如在凝结物质系统中的晶格上进行隧穿或量子磁化模型的相互作用。但是，当前的量子模拟器要么几乎没有实用的量子位，要么仅限于解决一些特定问题，例如固定几何形状上的特定量子模型。我的研究计划涉及这两个问题，并具有最终的目标，即建立一个量子模拟器，其中一个超过一百个被困的离子量表可以在单个量子台和之间的互动级别上进行编程。在接下来的5年中，我们的研究将由研究生，博士后研究员和本科研究人员进行两次平行的努力进行。第一项努力旨在实现大约十yb+离子量子的任意可编程的Qubit量相互作用。这将使模拟器能够超越离子链的物理几何形状，并在可重新配置的晶格几何形状上求解量子动力学。我们将使用数字光投影（DLP）技术开发一种新型的全息光学方法，以单独解决单个离子。第二次努力旨在将系统规模提高到数十个量子位。为此，我们将开发一个双物种量子模拟器（Yb+/ba+），Yb+作为Qubits和Ba+作为冷却剂，以增强量子相干性。将来，两项研究工作将结合在一起，以实现任意编程的大量子系统。HQP将在广泛的主题中进行培训，包括高功率激光器，光学，电子产品，DLP技术，超高真空，离子陷阱，光谱，光谱，量子信息科学，量子信息科学，量子多物理学和ATOMICTICT和ATOMICTICT和ATOMICIC和ATOMICICS，这些培训将为HQP做好准备，以供未来的职业选择，包括学术界和行业。该研究计划将在量子信息领域贡献新的基本和技术进步，并将加拿大作为量子信息研究的全球领导者，因为世界上只有少数高级量子模拟器。人才库和专业知识创造的将通过为快速增长的量子技术领域做出贡献，从而促进加拿大的经济，这有望在不久的将来从根本上改变我们的经济和社会。
