The Project

Physics and applications of semiconductor quantum-dot spin qubits.

Semiconductor quantum dots, known as artificial atoms, are nanometer-sized semiconductor crystals capable of trapping individual electrons. These nanostructures hold great promise for the development of a new generation of quantum computing and communication devices. The quantised magnetic (spin) state of the electron forms a qubit. Such qubits can store and process quantum information with efficiency inaccessible to any classical digital computer. The well-developed semiconductor technologies and the small size of the quantum dots offer pathways to large-scale integrated quantum circuits.

Recent breakthroughs in semiconductor nanotechnology resulted in a new generation of quantum dots, where quantum information processing is possible not only with electron spin qubits but also with subatomic magnetic states of the crystal lattice nuclei [see recent publications 1-5]. In this experimental project you will join a rapidly developing field of semiconductor spin qubits.  The aim of your work will be to explore the fundamental physics of quantum coherence and entanglement, as well as to develop prototype quantum computing protocols and spin-qubit devices. You will work in a state-of-the-art experimental laboratory equipped with modern cryogenic systems, superconducting high-field magnets, lasers, optical and radio-electronic equipment. During this project you will learn a wide range of transferable skills in the areas of quantum science, opto-electronic engineering, data analysis, automation and control systems, numerical modelling, and semiconductor device fabrication. If you have further questions about the project or the application process, please contact Dr Evgeny Chekhovich e.chekhovich@sussex.ac.uk.
