In circuit QED, a superconducting qubit is coupled to a microwave resonator, implementing cavity QED in an electrical circuit and providing a useful basis for superconducting circuit quantum computing. In Oxford we have recently developed a coaxial architecture of circuit QED which enables 2D grids of qubits to be implemented while keeping control and measurement wiring out of the qubit plane, enabling multi-qubit circuits to be developed without a requirement for complex on-chip wiring. This project will build on this realization to develop grids of 9-16 qubits to demonstrate the architecture's potential to scale up to a level that implements practical quantum computing. The aims of the project will be to build, measure and understand the behavior of 9-16 qubit circuits, and to explore methods to implement multi-qubit couplings and of quantum logic gates in such circuits. The student will work in collaboration with several other students and postdocs, and the team as a whole will work towards demonstrating quantum error correction and universal quantum computation in the coaxial architecture. This project falls within the EPSRC research areas of 'Quantum Optics and Information' and 'Quantum Devices, Components and Systems

在电路QED中，超导量子比特被耦合到微波谐振器，在电路中实现腔QED，并为超导电路量子计算提供了有用的基础。在牛津大学，我们最近开发了一种电路QED的同轴架构，该架构能够实现量子位的2D网格，同时将控制和测量布线保持在量子位平面之外，从而能够开发多量子位电路，而不需要复杂的片上布线。该项目将在此实现的基础上开发9-16个量子位的网格，以展示该架构扩展到实现实际量子计算的水平的潜力。该项目的目标是构建，测量和理解9-16量子位电路的行为，并探索在此类电路中实现多量子位耦合和量子逻辑门的方法。该学生将与其他几名学生和博士后合作，整个团队将致力于在同轴架构中展示量子纠错和通用量子计算。该项目属于EPSRC的“量子光学与信息”和“量子器件、组件和系统”研究领域的福尔斯
