Silverstone group (Big Photon Lab)

Research interests and activities

Large-scale quantum devices—quantum computers and simulators, sensing and communication networks—need a large variety of new optical technology. The Big Photon Lab, within Bristol’s QET Labs, is working to develop this underpinning technology and overcome barriers to building big quantum photonics. Our approach uses mass-manufacturable, miniature, and reliable silicon waveguides, carrying low-loss mid-infrared light (big photons), and integrates these with bespoke electronic control. Our work spans from the development of quantum computer architectures to the microscopic details of photonic and transistor design.

We develop components and integrate them into systems:

  • Photon-pair sources
  • Electro-optic modulators
  • Single-photon detectors
  • Large interferometers
  • Electronic control systems

We design architecture that puts our components to use, and which helps us understand where the weakest building blocks lie.
