Canada Excellence Research Chair in Quantum Information Processing

量子信息处理（QIP）是一种新的技术范式，它使用量子物理定律来操纵信息。 量子物理对信息处理提出了根本性的限制。 通过构建量子计算机、量子通信系统、量子传感器和执行器，我们有效地达到了功率和精度的极限。 对于许多任务来说，这个量子极限远远超过了受经典物理定律约束的设备的能力。 滑铁卢大学（UW）的量子计算研究所（IQC）将科学家和工程师聚集在一个卓越的QIP研究国际中心。 Cory教授加入IQC/UW将为该中心提供实现有用的量子处理器的途径。 量子信息处理发展的下一步是设计实用的量子传感器和执行器。 这些将是导航和控制微观量子世界的工具。 它们将成为未来量子计算机的基石。科里教授的研究兴趣是开发和实施实现这些第一代量子设备所需的工程。在过去的几年里，他的团队已经展示了量子致动器，其中光子或电子自旋的相干控制被用来对更大的核自旋池进行相干控制。 他们已经表明，这种控制可以通过量子纠错来改进，并且他们已经引入了纠缠辅助计量学的概念，作为采用量子纠缠来提高测量的灵敏度和精度的一种手段。 在IQC，Cory教授将建立一个独特的实验设施来设计，制造和部署量子设备。他的工作的一个新特点是认识到QIP可以提供直接的社会效益。 在这个项目中，我们将开发新的干涉测量方法，单自旋测量和基于QIP的陀螺仪。

Quantum Information Processing (QIP) is a new technological paradigm that uses the laws of quantum physics to manipulate information. Quantum physics poses the fundamental limits to information processing. By building quantum computers, quantum communication systems, quantum sensors and actuators, we effectively reach the ultimate limits in power and accuracy. For many tasks this quantum limit far exceeds the capacities of devices that are constrained to function by the classical laws of physics. The Institute for Quantum Computing (IQC) at the University of Waterloo (UW) brings together scientists and engineers in an international center of excellence for QIP research. Professor Cory’s addition to IQC/UW will provide the centre with a path to realizing useful quantum processors. The next step in the development of quantum information processing is to engineer practical quantum sensors and actuators. These will be the tools for navigating and controlling the microscopic quantum world. They will form the building blocks for future quantum computers. Professor Cory’s research interests are to develop and implement the engineering necessary to realize these first generation quantum devices. Over the past few years his group has demonstrated quantum actuators in which coherent control of photons or electron spins are used to have coherent control over a larger pool of nuclear spins. They have shown that such control can be improved through quantum error correction, and they have introduced the concepts of entanglement-assisted metrology as a means of employing quantum entanglement to improve the sensitivity and precision of a measurement. At IQC Professor Cory will build a unique experimental facility to design, fabricate and deploy quantum devices. A novel feature of his work has been to realize that QIP can provide immediate societal benefits. During this project we will develop new methods for interferometry, single spin measurement and gyroscopes based on QIP.
