标题： Generation and sampling of quantum states of light in a silicon chip

摘要： 实现量子算法的大实例需要在支持不同组件集成的硬件平台上处理许多量子信息载体。 虽然已建立的半导体制造工艺可以集成许多光子组件，但许多光子的生成和算法处理一直是集成光子学中的瓶颈。 在这里，我们报告了在量子采样算法中芯片上生成和处理最多八光子的光量子态。 通过在不同的光学泵浦模式之间切换，我们在同一硅芯片上实现了散射、高斯和标准玻色子采样协议，该芯片集成了线性和非线性光子电路。 我们利用这些结果来对计算分子振动光谱的量子算法进行基准测试。 我们的技术可以轻松扩展，用于具有数十光子的专用量子算法的芯片级实现，这为相对于传统计算机的效率优势指明了方向。 显示英文摘要

摘要： Implementing large instances of quantum algorithms requires the processing of many quantum information carriers in a hardware platform that supports the integration of different components. While established semiconductor fabrication processes can integrate many photonic components, the generation and algorithmic processing of many photons has been a bottleneck in integrated photonics. Here we report the on-chip generation and processing of quantum states of light with up to eight photons in quantum sampling algorithms. Switching between different optical pumping regimes, we implement the Scattershot, Gaussian and standard boson sampling protocols in the same silicon chip, which integrates linear and nonlinear photonic circuitry. We use these results to benchmark a quantum algorithm for calculating molecular vibronic spectra. Our techniques can be readily scaled for the on-chip implementation of specialised quantum algorithms with tens of photons, pointing the way to efficiency advantages over conventional computers.
