量子信息科学旨在利用独特的量子力学特性来增强测量和信息技术，并探索量子物理学的基本方面。在量子计算的各种方法中[1]，光子因其低噪声特性和易于在单量子位水平上操作而特别有吸引力[2，3]。在光子中编码量子信息也是量子通信、计量学（例如，[4])测量（例如，[5])以及其他量子技术[6]。然而，用体光学器件实现光量子电路已经达到了实际的极限。我们已经开发了一种集成波导方法来实现光子量子电路的高性能，小型化和可扩展性[7]。在这里，我们报告了关键量子光子电路的高保真硅基硅集成光学实现，包括双光子量子干涉和受控非逻辑门[8]。我们已经证明了多达四个光子在芯片上的控制操作，包括高保真单量子位操作，使用光刻图案化的电阻移相器[9]。我们已经使用这种架构来实现Shor的量子因子分解算法的小规模编译版本[10]，展示了从六光子输入[11]，可重新配置的双量子位电路[12]以及组合波导光子电路与超导单光子探测器[13]中产生可调谐四光子纠缠态的先驱。我们描述了具有多达八个输入和输出的多模干涉设备中的复杂量子干涉行为[14]，以及耦合波导阵列中相关粒子的量子行走[15]。最后，我们概述了我们最近在量子测量[16，17]和金刚石[18，19]以及非线性[20，21]光子源的基本方面的工作。

Quantum information science aims to harness uniquely quantum mechanical properties to enhance measurement and information technologies, and to explore fundamental aspects of quantum physics. Of the various approaches to quantum computing [1], photons are particularly appealing for their low-noise properties and ease of manipulation at the single qubit level [2,3]. Encoding quantum information in photons is also an appealing approach to quantum communication, metrology (eg. [4]), measurement (eg. [5]) and other quantum technologies [6]. However, the implementation of optical quantum circuits with bulk optics has reached practical limits. We have developed an integrated waveguide approach to photonic quantum circuits for high performance, miniaturization and scalability [7]. Here we report high-fidelity silica-on-silicon integrated optical realizations of key quantum photonic circuits, including two-photon quantum interference and a controlled-NOT logic gate [8]. We have demonstrated controlled manipulation of up to four photons on-chip, including highfidelity single qubit operations, using a lithographically patterned resistive phase shifter [9]. We have used this architecture to implement a small-scale compiled version of Shor's quantum factoring algorithm [10], demonstrated heralded generation of tunable four photon entangled states from a six photon input [11], a reconfigurable two-qubit circuit [12], and combined waveguide photonic circuits with superconducting single photon detectors [13]. We describe complex quantum interference behavior in multi-mode interference devices with up to eight inputs and outputs [14], and quantum walks of correlated particles in arrays of coupled waveguides [15]. Finally, we give an overview of our recent work on fundamental aspects of quantum measurement [16,17] and diamond [18,19] and nonlinear [20,21] photon sources.
