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.x000D
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.x000D
