Nanoscale semiconductor structures have attracted considerable attention for potential applications in quantum information processing, energy harvesting, and photonics. Quantum dots, known as artificial atoms, are nanometer-sized semiconductor crystals capable of holding individual electrons. These nanostructures are particularly promising for quantum information processing hardware: the quantized magnetic states of the electrons can be used to store and process information with efficiency inaccessible to any classical digital computer, while 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 development of a new type of quantum dots. Unlike the previous generations, these new gallium arsenide quantum dots are free from internal strain, allowing the quantum magnetic states of the crystal atoms to be used as a resource. The aim of your work will be to explore experimentally the fundamental physics of quantum thermodynamics, many-body quantum coherence and entanglement in these unique nanostructures. Using this knowledge, you will develop prototype quantum dot devices that exploit magnetic states of electrons and atoms for quantum information processing protocols.
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 radio-electronic and optical engineering, control systems engineering and automation, quantum physics, data analysis, numerical simulations, and semiconductor fabrication technology.
You are expected to have or about to complete a degree in the relevant area of physics or engineering. If you have further questions about the project or the application process please contact Dr Evgeny Chekhovich [email protected]
