Canada Excellence Research Chair in Quantum Signal Processing

量子信息是物理学、计算机科学和工程学相结合的新兴研究领域。 它旨在利用量子力学的非直观定律以革命性的方式编码，传输和处理信息：量子计算机可以以指数级的速度执行某些任务，而量子密码术可以实现无条件的安全私人通信。由于它们对我们社会的巨大潜在影响，全世界都在努力实现量子技术。这把椅子将在研究的新领域，量子信号处理的前沿，这将成为这一努力的关键组成部分之一。 所有的商业信息处理器都围绕着固态物理。这也是构建量子信息处理器最有希望的途径，但在操作和读出过程中影响这些系统的电子噪声是一个主要障碍。量子信号处理将借鉴低温下微电子元件中非高斯噪声的研究，这是由拟议主席开创的研究领域，以加深我们对这种噪声的理解，并改善量子设备和经典设备之间的接口，为固态可扩展量子技术铺平道路。固态器件中噪声机制的详细知识-特别是非高斯噪声-在微电子领域有额外的应用，在微电子领域它提供了一种非侵入性元件表征的工具，在通信技术领域它可以提供编码、分析和加密信息的新方法。

Quantum information is an emerging field of research combining physics, computer science, and engineering. It aims at harnessing the very non-intuitive laws of quantum mechanics to encode, transmit, and process information in revolutionary ways: quantum computers can execute certain tasks exponentially faster that currently possible while quantum cryptography enables unconditional secure private communications. Because of their immense potential impacts on our society, there is a worldwide effort to realize quantum technologies. This Chair will be at the frontier of the new field of research, quantum signal processing, that will become one of the crucial components of this effort. All commercial information processors revolve around solid-state physics. This is also the most promising avenue to build a quantum information processor, but the electronic noise affecting these systems during their operation and readout represents a major obstacle. Quantum signal processing will borrow from the study of non-Gaussian noise in micro-electronic components at low temperature, a field of research pioneered by the proposed Chairholder, to deepen our understanding of this noise and improve the interfaces between quantum devices and classical apparatus, paving the way to scalable quantum technologies in the solid-state. Detailed knowledge of noise mechanisms in solid-state devices---and particularly non-Gaussian noise---has additional application in the field of micro-electronics where it provides a tool for non-invasive component characterization and in communication technologies where it could offer new ways to encode, analyze and encrypt information.
