Photonic approaches to quantum information science and technology promise new scientific discoveries and new applications. Linear optics underpins all of these protocols and the advent of integrated quantum photonics has has brought with it a step change in complexity and control over quantum photonic systems. In this talk we present recent progress towards large-scale silicon-based quantum photonic processors, including fully reconfigurable linear optical circuits capable of rapidly “dialling up” arbitrary quantum operations, and integrated single photon sources based upon spontaneous four-wave mixing. These results demonstrate quantum photonic processors as both a versatile testbed for prototyping new linear optical protocols and as a route towards large-scale quantum information processing, pointing the way to applications across fundamental science and quantum technologies.
