Dr John Bartholomew

• Chief Investigator
• The University of Sydney

Dr John Bartholomew is developing technologies to create a quantum internet. Currently he is focusing on using crystals containing the rare-earth element erbium to integrate optical photons, microwave photons, and solid-state spins in a single quantum system.

John received his PhD in physics from the Australian National University in 2014 working with Associate Professor Matthew Sellars in the Solid State Spectroscopy Group. The focus of John’s thesis was advancing the miniaturisation and scalability of rare-earth ion systems for quantum information science. In 2015 he took up a research position with the Crystal and Quantum State Dynamics Group (Chimie Paristech, France) to study the quantum optical properties of rare-earth ions in nanoparticles. The following year John received the American Australian Association Northrop Grumman Fellowship to join the Nanoscale and Quantum Optics Group at the California Institute of Technology (Caltech). Following three and a half years in Pasadena, John returned to Australia commencing as the Director of the Quantum Integration Laboratory in the second half of 2019.
