My research is in theoretical optical quantum information processing. I am interested in physical architectures and applications for optical quantum devices: How can we use quantum light for practical quantum communication, metrology, imaging, and computing.

  • Lecturer, University of Sheffield (2007-present)
Research interests

Any practical distributed, long-distance quantum technology—such as the quantum Internet—will most likely involve light as a quantum information carrier. It is therefore important to understand the capabilities and limitations of photons as quantum bits.

Broadly speaking, my research falls into three categories:

  • linear optical quantum computing
  • hybrid quantum computing with light and matter qubits
  • quantum metrology
