UKRI Studentship Eligibility
The eligibility criteria for UKRI funding has changed for studentships commencing in the 2021/22 academic year. Now, all home and international students are eligible to apply for UKRI funding which will cover the full stipend and tuition fees at the home rate (not the international rate). Under the new criteria, UKRI have stipulated a maximum percentage of international students that can be recruited each year against individual training grants. This will be managed at the institutional level for all EPSRC DTP and ICASE grants. For EPSRC CDT grants, this will be managed by the individual CDT administrative/management team. For ESRC and AHRC studentships the final funding decision will be made by the respective grant holder.
To be classed as a home student, applicants must meet the following criteria:
- Be a UK national (meeting residency requirements), or
- Have settled status, or
- Have pre-settled status (meeting residency requirements), or
- Have indefinite leave to remain or enter.
The residency requirements are based on the Education (Fees and Awards) (England) Regulations 2007 and subsequent amendments. Normally to be eligible for a full award a student must have no restrictions on how long they can stay in the UK and have been ordinarily resident in the UK for at least 3 years prior to the start of the studentship (with some further constraint regarding residence for education).
If a student does not meet the criteria above, they will be classed as an international student. The international portion of the tuition fee cannot be funded by the UKRI grant and must be covered from other sources. International students are permitted to self-fund the difference between the home and international fee rates.
A successful implementation of a fault tolerant quantum computer based on solid state spin qubits will most likely involve their arrangement in a regular lattice. Recent technological breakthroughs have enabled the creation of such scalable quantum systems with one of the most prominent being the platform of site-controlled quantum dots. The high spectral quality, deterministic positioning and all-optical ultrafast addressability of long lived spins in these quantum emitters, make them very attractive candidates as a platform for quantum hardware.
In order to enable scalable interactions within such hardware it is necessary to engineer and control the spin states. In this project we will investigate various approaches for on-demand engineering of the trapped spin states in charged quantum dots through a series of coherent control experiments that will explore how the different approaches affect the performance of all optically operated universal single qubit gates. The samples that we will investigate initially are self-assembled InGaAs quantum dots with delta doping for charging while at a later stage we will investigate substrate nanopatterned and nanoimprint lithography site-controlled quantum dots, provided by our national and international collaborators.
This experimental work will require the development of an all optical coherent control experiment for individual quantum dots and the candidate will have the unique opportunity to develop the experimental setup side by side with the PI getting extremely valuable hands-on experience and developing unique experimental skills.
Parallel to the development of the experimental setup, the work will involve the spectroscopic characterization of the self-assembled and site-controlled quantum dot samples utilizing magnetic spectroscopy techniques at liquid helium temperatures while for the characterization of the universal quantum gates the work will involve advanced all-optical spin control techniques utilizing a combination of pulsed and CW lasers.
We are looking for a highly motivated experimentalist with physics background and general knowledge and understanding of optics, lasers and semiconductor physics. Prior involvement to similar experimental activities is highly sought for.
Please provide the reasons you would like to join our group and your academic CV.
