The overall objective of this 3-year long project is to utilize a proven, mass-production sub-14nm CMOS foundry technology to develop the critical building blocks required for quantum computing. This will be carried out in close collaboration with a global leader in the this field, namely Intel, in Canada. The expected outcomes of the proposed research include the atomic-level simulation, design, fabrication and experimental characterization of a set of Si and SiGe electron and hole coupled qubits utilizing the coupled quantum-dot approach, along with the associated ultra-low-temperature microwave and mm-wave analog-mixed-signal spin-manipulation and spin-readout electronic circuits. In parallel with the electronic qubits, we plan to also deliver, for the first time, the capabilities of generating and coupling optical quantum states to the aforementioned qubits within the same material CMOS platform. This, in turn, empowers the connectivity of this quantum computing architecture for future extended-range interconnection between the electronic quantum computing logic blocks through photons. The optical qubits will be based on entangled and hybrid entangled photons possessing energies that can interact, hence couple, with the electronic qubits. At present, there is no practical, integrated fashion by which photons can be generated and manipulated to interact with electronic Si qubits.The qubit structures and the associated analog-mixed-signal electronic circuits proposed here have the greatest long-term (10 years) chance of operation at room temperature in a large volume CMOS-like technology platform. This would dramatically revolutionize the field of quantum computing, making it possible to put a mobile quantum computer with the power of today's largest supercomputer in everyone's pocket and at the price of today's smartphones.

这个三年长的项目的总体目标是利用经过验证的，群众生产的低于14nm CMOS铸造技术来开发量子计算所需的关键构建块。这将与该领域的全球领导者（即加拿大英特尔）密切合作。拟议的研究的预期结果包括一组SI和SIGE电子和孔偶联量子的原子级模拟，设计，制造和实验表征，以及相关的超低量子点方法，以及相关的超低 - 灵活的微波微波和MM-Wave-M-Wave-Mixed-Mixed-Mixed-Signal Spinal-Spinic rock-spinonic rock-Rread和Spinonic road Rread。与电子Qubits并行，我们计划首次传递将光学量子状态生成和耦合到同一材料CMOS平台中上述Qubits的功能。反过来，这赋予了该量子计算体系结构的连接性，以通过光子通过光子块之间的电子量子计算逻辑块之间的将来的扩展范围互连。光量子位将基于具有可以相互作用的能量的纠缠和杂化纠缠的光子，因此夫妇与电子量子台相互作用。目前，还没有实用的集成方式，可以通过这些方式生成并操纵光子与电子Si量表相互作用。这里提出的量子结构和相关的模拟混合信号信号电路具有很大的长期（10年）在大型CMOS类似CMOS的技术平台上在室温下运行的最大机会。这将极大地彻底改变了量子计算领域，从而可以将带有当今最大超级计算机的功能的移动量子计算机放在每个人的口袋中，并以当今的智能手机的价格。
