Type of award
The Sussex Centre for Quantum Technologies is focused on fundamental quantum science and on the development of novel quantum technologies. It hosts several experimental and theoretical groups that cover an extensive research area, such as microwave quantum sensors, quantum computation and communications with trapped ions, theoretical quantum optics, quantum metrology, ultra-cold atoms in atom chips, and others. Sussex offers a unique environment for highly motivated PhD candidates, providing advanced training in a wide variety of experimental and theoretical skills.
About the project:
This PhD project centres on the development of a Quantum Microwave Sensor for fundamental Physics applications, explicitly for the planned future measurement of the neutrino mass. The neutrino mass is the last of the fundamental constants of the standard model which has not yet been measured. Neutrino flavour oscillations and cosmology observations set an ultimate boundary at , or in the case of “inverted” or “normal” ordering of the neutrino mass hierarchy, respectively. A novel approach for measuring has recently been proposed: the so-called Cyclotron Resonance Spectroscopy (CRES) technique. This can deliver the neutrino mass by measuring the microwave radiation emitted by the electrons resulting from tritium beta-decay. To achieve the needed accuracy of , the CRES technique requires an ultra-accurate microwave sensor, which should be capable of detecting tiny signals of a few tens of microwave photons. At Sussex we are developing such a quantum microwave sensor using our novel “geonium chip” ion trap. This will use a trapped electron (so-called “geonium atom”) as the quantum microwave sensor. The geonium atom is capable of measuring the ultimate limit of single microwave photons and will allow for the CRES technique to reach its full potential. Further applications of our quantum microwave sensor are Quantum Radar, Microwave Microscopy, and Quantum Microwave Imaging.
Skills and training:
The PhD candidate will work with an existing experimental cryogenic ion trap setup at the University of Sussex, www.geoniumchip.org. The successful candidate will receive training in ion trap technology, magnetic fields design with superconductors, cryogenics, RF electronics, microwave engineering, and quantum optics. There will also be opportunities to present work at international conferences, as the project involves international collaboration with world-class groups in fundamental physics and quantum technology, as well as private companies.
An important part of this PhD project is the skills development and training. Local training through lecture courses, transferable skills training modules and practical training in the laboratory will be complemented by training events offered through SEPNet. These include workshops, training schools and networking opportunities.
Applicants must hold, or expect to hold, at least a UK upper second class degree (or non-UK equivalent qualification) in Physics, or a closely-related area, or else a lower second class degree followed by a relevant Master's degree.
If you are not a UK national, nor a EU national with UK settled/pre-settled status, you will need to apply for a student study visa before admission.
This award is open to UK and International students.
