Lilian Childress

Appointment

  • Fellow
  • Quantum Information Science

About

Lilian Childress’ research applies notions from quantum optics and atomic physics to condensed matter systems, notably defect centres in diamond.

Over the last decade, her work has examined how electronic and nuclear spins in diamond can serve as a platform for quantum information processing and quantum-enhanced sensing. Her group at McGill is focused on two primary directions: (1) creating a spin-photon interface by integrating diamond defects into fiber-based micro-cavities and (2) investigating dynamics of spin-transfer-driven nanomagnets using defect-based probes. These projects could help to create a platform for a quantum network using photons and spins in diamond, and provide new insight into magnetic systems that play a critical role in classical (and perhaps someday quantum) computing hardware. Other recent interests include optimal qubit readout, charge state dynamics of defect centres, opto-mechanics with superfluid helium, and micro-cavity-enhanced sensing.
