About
Dr. Patrick Ledingham is an experimental quantum physicist actively involved in research aimed at advancing scalable quantum technology using single photons.
His work has been centered on exploring light-matter interactions within diverse material systems, including rare earth ion-doped media, defects in diamond, alkali vapors, and semiconductor quantum dots.
Dr. Ledingham's primary focus is on developing the capability to store and retrieve quantum optical states on demand, essentially creating a quantum optical memory.
He leads the Hybrid Quantum Networks Laboratory, specializing in broadband (>GHz) quantum memory protocols within atomic ensembles, spanning both room temperature and cryogenic platforms, with a particular emphasis on establishing interfaces with heralded and deterministic single photon sources.

Current research
Dr Patrick Ledingham's research interests lie in quantum light-matter interactions between atomic ensembles (based on rare-earth-ion-doped solids and alkali vapours) and single photons (generated from quantum dots and nonlinear media). Our research aims to merge these disparate systems to form large-scale quantum photonic networks for the processing of quantum information over global distances.
