项目摘要

Quantum information science has developed over the last two decades into a core research area of interest around the world. Game-changing applications in communication, computing, simulation and metrology are expected to develop over the next couple of decades as a full-fledged quantum information technology industry emerges. A key open question is, "can a solid-state approach to building scalable quantum processors be viable?" Such an approach would benefit greatly from the fabrication expertise of existing semiconductor-based information technologies to achieve powerful quantum information processors at reasonable cost. Nanoelectronics devices working at the single electron level have tremendous potential to fill this role, and this project will address the key challenges to making these devices viable building blocks. Challenges in the solid-state include maintaining quantum coherence, performing reliable measurements, and the reproducibility (yield) of devices fabricated at the nanoscale. Our approaches marry the charge and spin aspects of the electron to get the "best of both worlds" in terms of coherence and controllability. The ideas underlying these approaches are powerful, and our experiments will put them to the test. Canada's competitive edge in the the future world of quantum technologies depends critically on the innovations that will come from testing these ideas.

在过去的二十年中，量子信息科学发展到了全球感兴趣的核心研究领域。随着成熟的量子信息技术行业的出现，预计在接下来的几十年中，可以在接下来的几十年中发展进行游戏规则的应用程序。一个关键的开放问题是，“固定方法可以可行地构建可扩展量子处理器吗？”这种方法将从现有基于半导体的信息技术的制造专业知识中受益匪浅，以合理的成本实现强大的量子信息处理器。在单电子级别工作的纳米电子设备具有巨大的潜力来填补这一角色，并且该项目将解决使这些设备可行的构建块的关键挑战。固态的挑战包括保持量子相干性，执行可靠的测量以及在纳米级制造的设备的可重复性（产量）。我们的方法嫁给了电子的电荷和旋转方面，以在连贯性和可控性方面获得“两者的最佳”。这些方法基础的想法是有力的，我们的实验将使它们进行测试。加拿大在量子技术的未来世界中的竞争优势取决于测试这些想法所带来的创新。
