Steven Touzard Group

Our group is focused on designing and building quantum technologies with an emphasis on quantum networks. Our experimental platforms include superconducting circuits, rare-earth ions in solid-state and integrated photonics. Our goals are to:

  • Rethink quantum network chips: we invent, simulate and fabricate novel chips to entangle superconducting circuits with telecommunication photons ready to be launched in commercial optical fibers and form a quantum network.
  • Develop quantum control tools: we investigate innovative protocols to operate fast quantum networks. These protocols are implemented with our fast electronics and stable lasers at ambient and cryogenic temperatures.
  • Establish new fabrication techniques: we develop new methods to safely combine the best of leading quantum technologies: superconducting circuits, rare-earth ions and integrated optics.
  • Build testbeds for quantum networks: we characterize the uniquely quantum correlations between a superconducting qubit at cryogenic temperatures and a traveling telecom photon at room temperature. This testbed will readily be deployed in commercial quantum networks

Steven earned his PhD from Yale University from the group of Michel Devoret. His work focused on stabilising bosonic codes in superconducting circuits. He then did a postdoc at the National University of Singapore on quantum information processing with neutral strontium atoms. Steven also worked as a consultant for quantum computing companies Alice&Bob and Xanadu.

In 2021, Steven was awarded the National Research Foundation Fellowship (Class of 2022) to start a new research initiative in Singapore focusing on building quantum networks of superconducting circuits. He was then appointed as a Presidential Young Professor in the Department of Materials Science and Engineering as well as the Department of Physics.
