The aim of this proposal is to experimentally validate software modules allowing the design and scale up of silicon based quantum computers and sensors. Our industrial partner, NanoAcademic Technologies (Montreal) is currently in the process of developing a Technology Computer Aided Design tool (TCAD) for quantum technology - QTCAD, with focus on simulating silicon based spin qubits for quantum computing hardware. Qubits in silicon can be implemented with atomically positioned dopant atoms. Silicon is an attractive material for quantum computing, as it provides for very long coherence times (i.e. quantum instead of classical properties persist for relatively long times). Furthermore, the vast experience of the semiconductor industry can be harnessed for future scale up. In this proposal, in collaboration with partners in the UK, we will position dopant atoms in silicon in atomic precise patterns using scanning tunneling microscopy. At McGill, we will use cryogenic atomic force microscopy in a magnetic field to characterize the position and perform spectroscopy on individual and coupled dopant atoms to measure their energy levels as well as coupling strength and quantum characteristics. Comparing the experimental values with the result of the computer simulations will allow validation of the software modules. Each of the two Canadian and two UK partners contribute complimentary and unique expertise needed to achieve our goals. This international collaboration between academics and companies in Canada and the UK will allow excellent training of students, build strong connections between academics and companies in Canada and the UK in the field of quantum technology and lead to high impact science.

该提案的目的是通过实验验证软件模块，从而允许设计和扩大基于硅的量子计算机和传感器。我们的工业合作伙伴 NanoAcademic Technologies（蒙特利尔）目前正在开发用于量子技术的技术计算机辅助设计工具 (TCAD) - QTCAD，重点是模拟用于量子计算硬件的基于硅的自旋量子位。硅中的量子位可以通过原子定位的掺杂原子来实现。硅对于量子计算来说是一种有吸引力的材料，因为它提供了非常长的相干时间（即量子而不是经典特性持续相对较长的时间）。此外，半导体行业的丰富经验可以用于未来的规模化。 在这项提案中，我们将与英国的合作伙伴合作，使用扫描隧道显微镜以原子精确图案定位硅中的掺杂原子。在麦吉尔，我们将在磁场中使用低温原子力显微镜来表征位置，并对单个和耦合的掺杂原子进行光谱分析，以测量它们的能级以及耦合强度和量子特性。将实验值与计算机模拟结果进行比较将可以验证软件模块。两个加拿大和两个英国合作伙伴都贡献了实现我们目标所需的互补和独特的专业知识。加拿大和英国的学者和公司之间的这种国际合作将为学生提供良好的培训，在加拿大和英国的学者和公司之间在量子技术领域建立牢固的联系，并带来高影响力的科学。
