(Full-Time/Indefinite with End Date)
Interview date: Tuesday 1st September 2026
We are seeking an enthusiastic postdoctoral researcher for a new project to develop superconducting electronics using graphene Josephson junctions. Graphene Josephson junctions (G-JJs) offer the opportunity to build superconducting electronics that can be controlled electrostatically, which avoids magnetic fields that can interfere with other superconducting devices, such as quantum sensors or qubits. Until recently, the fabrication of G-JJs has been limited to mechanical exfoliation, which lacks reproducibility and is time-consuming and inefficient. VTT Technical Research Centre in Finland have developed a wafer scale fabrication process for fabricating G-JJs across an entire wafer, up to 200mm with plans to scale up to 300mm.
The SuperICQ consortium is a recently funded EU Pathfinder Open project that aims to develop a host of superconducting electronics using this new process and to integrate these with superconducting qubits. At Lancaster we will be characterising individual junctions, designing and testing parametric amplifiers, characterising tuneable resonators and demonstrating multiplexed qubit readout. As a member of the consortium you will also collaborate with partners at VTT (Finland), Aalto (Finland) and Chalmers (Sweden).
Lancaster is a major player in superconducting quantum devices in the UK and benefits from extensive nanofabrication, cryogenic, and electronics infrastructure. You will work in the Quantum Technology Centre at the Physics Department of Lancaster University and will travel as necessary to liaise with project partners and to attend national and international workshops and conferences.
