Project description
Scalable approaches towards quantum computing chips
Scalable approaches are key to realising practical, reliable quantum computers in the future. Funded by the Marie Skłodowska-Curie Actions programme, the DEMETER project plans to demonstrate an innovative scalable qubit platform using the emergent architecture of rhombic quadruple quantum dots and germanium as a platform. Building on advances in electronics design and fabrication, researchers will develop radio-frequency single electron transistors and gate-based sensors for qubit readout. The ultimate aim is to achieve high qubit coherence times, fast qubit operation and readout and pave the way towards scalable fabrication of quantum microchips.
Objective
I propose a 24-month MSCA Postdoctoral Fellowship in experimental condensed matter physics to overcome limitations in coherence time, single-gate operation frequency, and scalable readout associated with challenges in realising quantum computers. DEMETER builds on the complementarity of my strengths, the leading fabrication expertise and infrastructure at my Host, Tyndall National Institute, and the know-how in quantum information processing afforded by a secondment at the high-potential UK SME Quantum Motion. I will use Ge as an emerging quantum material platform to realise Ge-hole spin qubits in strained Ge/SiGe heterostructures and gate-defined RQQDs formed in the underlying Ge. DEMETER aims to demonstrate a beyond state-of-the art scalable qubit platform using the emergent architecture of Rhombic Quadruple Quantum Dots (RQQDs) and the Ge material platform. Using this novel architecture and exploiting advances in fabrication processes, rf-based novel techniques – that is rf single-electron transistor (RF-SET) and gate-based sensing for qubit readout will be implemented offering scalability through integration of both the qubit realization and control readout. My specific science and technology objectives are to achieve advances in the coherence time, fast qubit operation and fast readout, and to contribute towards the scalability of quantum microchips. My career development will benefit from the supervision of Dr Giorgos Fagas, an established leader at Tyndall, the Irish quantum technologies community and the EU landscape, and the research expertise in processing Ge nanostructures of Drs Duffy and Petkov. During my 2-month secondment, I will be supervised by Dr. Fernando Gonzalez-Zalba who is a leading researcher in gate-based sensing reflectometry. The goal of the Fellowship matches the urgent need to support the EU Quantum Technologies flagship and foster leading expertise in quantum computing.
