About This PhD Project

Project Description

A PhD studentship is available in the Quantum Devices group to measure, control and read out electron spin qubits defined in carbon nanotube quantum dots. The aim of the project is the generation and measurement of multi-qubit entanglement in these devices. Experimental work will involve device fabrication in a cleanroom environment and electrical measurements at mK temperatures in a dilution refrigerator using radio-frequency reflectometry for qubit readout and microwave techniques for qubit control. The work will be carried out at the London Centre for Nanotechnology (LCN) at UCL in the group of Dr. Mark Buitelaar in collaboration with a broader network of experimental and theoretical colleagues. The student will be expected to have a good first degree in physics, engineering or a related subject. The start date of the project is September 2019.

London Centre for Nanotechnology

The London Centre for Nanotechnology is an interdisciplinary joint enterprise between University College London and Imperial College London. In bringing together world-class infrastructure and leading nanotechnology research activities, the Centre aims to attain the critical mass to compete with the best facilities abroad. Research programmes are aligned to three key areas, namely Planet Care, Healthcare and Information Technology and exploit core competencies in biomedical, physical and engineering sciences.

The Centre occupies a purpose-built eight storey facility in Gordon Street, Bloomsbury, as well as extensive facilities within different departments at South Kensington. LCN researchers have access to state-of-the-art clean-room, characterisation, fabrication, manipulation and design laboratories. This experimental research is complemented by leading edge modelling, visualisation and theory.

LCN has strong relationships with the broader nanotechnology and commercial communities, and is involved in much major collaboration. As the world’s only such facility to be located in the heart of a metropolis, LCN has superb access to corporate, investment and industrial partners. LCN is at the forefront of training in nanotechnology, and has a strong media presence aimed at educating the public and bringing transparency to this emerging science.
