Architectures for quantum processors in heterogeneous integrated quantum photonics

风险表格中的项目描述供您适应：布里斯托在过去15年的研究一直处于量子技术发展的前沿，在量子传感、量子密码学、量子计算和模拟方面取得了突破。然而，为了提供通用的量子计算，这需要数千个量子位和超高保真度的操作，需要在可扩展的硬件中进行大量的基础研究。虽然单材料集成量子光子学（诸如硅光子学）已经实现了>10量子比特器件并且可以在晶片级制造，但是它本质上缺乏用于确定性光子生成的关键功能和用于光子-光子相互作用的中介;为了替代这些功能，使用自发光子发射和概率纠缠门，这导致多路复用电路中不可行的大开销。该博士将研究功能光子组件的异构集成架构，包括确定性光子源和量子逻辑的物质介导的光子-光子相互作用。

Project description from Risk Form for you to adapt: Bristol research over the last 15 years has been at the forefront of the development of quantum technologies, with breakthroughs in quantum sensing, quantum cryptography, and quantum computing and simulations. However, to deliver universal quantum computing, which requires thousands of qubits and ultra-high fidelity operations, significant basic research is needed in scalable hardware. While single-material integrated quantum photonics, such as silicon photonics, has achieved >10-qubit devices and is manufacturable at wafer scale, it intrinsically lacks the critical functionality for deterministic photon generation and a mediation for photon-photon interactions; to substitution for these functions, the spontaneous photon emission and probabilistic entangling gates are used, which results in unfeasibly large overheads in multiplexing circuitry. This PhD will investigate architectures for the heterogeneous integration of functional photonic components, including deterministic photon sources and matter mediated photon-photon interaction for quantum logic.
