PhD Studentship: Quantum Information with Mechanical Systems (QuIMS): Modelling Nonlinear Quantum Optomechanical Devices

Overview

The University of Exeter Department of Physics and Astronomy offers a 3.5-year PhD studentship titled Quantum Information with Mechanical Systems (QuIMS): Modelling Nonlinear Quantum Optomechanical Devices. The project investigates whether nanomechanical systems can serve as an alternative platform for quantum information processing and quantum-enhanced sensing. The research focuses on suspended graphene resonators integrated with superconducting microwave cavities to overcome limitations in coherence, control errors, and qubit connectivity. The studentship is embedded within the EPSRC-funded Quantum Information with Mechanical Systems programme and is funded by the EPSRC Engineering and Physical Sciences Research Council.

Requirements

The student will pursue a focused theoretical and computational research programme involving the development of analytical and numerical models of device dynamics. Previous nanofabrication experience is not required, as the primary contribution is computational. The researcher will examine how resonator geometry, phononic-crystal design, electrical control, quality factors, and coupling strengths influence performance, alongside practical limitations such as heating, dissipation, and decoherence. The work requires collaborating closely with quantum theorists, graphene-device researchers, and low-temperature experimental physicists.

What you get

The studentship covers university fees and provides a stipend of £21,805 per annum for the 2026/7 academic year. Expected outputs from the programme include documented research software, device-design principles, conference presentations, peer-reviewed publications, and a doctoral thesis, while building interdisciplinary knowledge in graphene nanodevices, superconducting circuits, and low-temperature quantum measurement.
