Biographical details

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.

Research interests

Creating connections between remote quantum systems will be central to building large scale quantum computers and probing fundamental quantum mechanics. Scaling up quantum entanglement beyond isolated systems will require high performance qubits, interfaces between qubits and photons, sources of entanglement and transducers to convert between different operating regimes. John's interest is building up sophisticated quantum networks throughengineering quantum hardware and leveraging these devices to discover new physics.

Teaching and supervision

In 2023, John is teaching Quantum nanoscience (Honours level: PHYS4126; Graduate level: PHYS5126). He is also coordinating the experimental project for Interdisciplinary Physics (3rd year: PHYS3888) in both Semesters 1 and 2. In Semester 1, students will partner with students from DATA3888 to build a computer-brain interface, and in Semester 2,students will partner with students from CHEM3888 to propose and investigate innovative applications of nuclear magnetic resonance (NMR).

As Director of the new Quantum Integration Lab housed in the Sydney Nanoscience Hub, John offers research projects in theoretical and experimental aspects of quantum networking. These typically focus on designing and creating interactions between photons and optically accessible spins embedded in crystals and can be tailored for all levels (Dalyell, SSP, Senior projects, Honours, MPhil, and PhD).
