EP-30b PhD - Quantum technologies with advanced site-controlled quantum dot structuresContract: Full Time/Fixed TermThe Epitaxy and Physics of Nanostructures ( ) group, Tyndall National Institution and University College Cork fund a PhD position for “Quantum technologies with advanced site-controlled quantum dot structures “.The Epitaxy and Physics of Nanostructures group is a well-established research team in Ireland focused on quantum technology research, quantum optics and device (epitaxial) growth by MOVPE. We are seeking highly self-motivated applicants with strong experimental attitude to apply for this position.Key Responsibilities and research objectivesThere is a growing interest in developing cryogenic devices for quantum technologies, so to overcome a number of limitations the community is facing in the quest for an efficient quantum processor. Site-controlled quantum dots (QDs) are excellent candidates for the mission, while facing challenges of their own. The EPN group is world leading the effort to establish advanced site-controlled QD technology, aiming at photonic mode control and enhancement (e.g. tailored cavities and/or waveguiding system), quantum light quality and entanglement in it various expressions (e.g. biexciton-exciton cascade, cluster states etc..).Recent results on the unique system developed at Tyndall were featured in major reviews, such as Nature Photonics (e.g. Gediminas Juska, et al. “Towards quantum dot based arrays of entangled photon emitters”, Nature Photonics 7, 527 (2013); T. H. Chung, et al. “Selective carrier injection into patterned arrays of pyramidal quantum dots for entangled photon light-emitting diodes”, Nature Photonics 10, 782 (2016)). Similarly, EPN has been at the forefront of growth understanding and modelling, see e.g.: V. Dimastrodonato, E. Pelucchi, and D. D. Vvedensky. "Self-limiting evolution of seeded quantum wires and dots on patterned substrates." Physical Review Letters 108.25 (2012): 256102; A. M. Gocalinska et al.,” Early stages of InP nanostructure formation on AlInAs”, Phys Rev. B 101, 165310 (2020) and E. E. Mura, et al., “Importance of Overcoming MOVPE Surface Evolution Instabilities for >1.3 μm Metamorphic Lasers on GaAs”, Cryst. Growth Des. 2021, 21, 4, 2068–2075The main focus of this position will be on two fronts: on one side participate to the quantum optic challenges of the developed QD based structures, by advancing photon correlation spectroscopy, dual resonant pumping, and, generally, methods for selectively address specific and unusual quantum dot resonances and their potential exploitation in quantum processing schemes. On the other hand, a strong effort will be put in developing quantum dot devices (e.g. cavities, photonic integration, especially with the QD category generally called as “small pitch” dots) suitable for the exploitation of quantum processing protocols.The work will include, in collaboration with the rest of the team, running the quantum optics laboratory, cleanroom processing and structural characterization techniques, such as AFM at various degrees depending on project developments.The PhD candidate is also expected to collaborate intensively with the rest of the EPN group on other subjects close to the PhD topics.Other responsibilities
