PhD Position in Quantum Dot Theory for Quantum Technologies: Developing Photonic Cluster State Sources

GJ-2 PhD Position in Quantum Dot Theory for Quantum Technologies

Contract: Full Time/Fixed Term

The Epitaxy and Physics of Nanostructures (EPN) group at Tyndall National Institution and University College Cork is offering a PhD position in theoretical quantum technologies with quantum dots.  The focus is on developing a photonic prototype device for multi-entangled photon sources, crucial for Quantum Information Processing.

About Us

The EPN group is renowned for its pioneering work in site-controlled quantum dots, with significant publications in Nature Photonics and Phys. Rev. Lett.  (see the seminal research works: G. Juska, et al. Nature Photonics 7, 527 (2013), T. H. Chung, et al. Nature Photonics 10, 782 (2016), V. Dimastrodonato, et al. Phys. Rev. Lett. 108, 256102 (2012)). We specialize in quantum technology research, quantum optics, and epitaxial growth by MOVPE.

Key Responsibilities and Research Objectives

Our project addresses the scalability bottleneck in photonic quantum information processing. Current technologies struggle with maintaining coherence and handling parallel calculations. Our approach leverages measurement-based quantum computing with multi-dimensional photonic cluster states.

We aim to develop a prototype source using uniquely scalable, site-controlled, paired semiconductor quantum dots (QDs). These customizable QDs offer precise engineering of molecular states, enabling two-dimensional states on-demand without the need for resource-heavy fusion gates.

Position description

  • Develop a symmetry-adapted simulation framework for site-controlled QDs.
  • Study and tailor single-particle states, exchange interactions, and external perturbations like magnetic fields.
  • Simulate time-resolved dynamics of QD systems, including resonant excitation schemes and spin-photon entangling processes.
  • Advisors: Dr. Stefan Schulz and Dr. Gediminas Juska

The candidate will engage closely with the EPN team, contributing to a collaborative, feedback-driven environment.

Additional Responsibilities

  • Participate in Education and Public Engagement activities.
  • Ensure compliance with Tyndall's Quality Management, and Health and Safety standards.
  • Perform additional duties as required within the scope of the post.

Essential Criteria

  • A first-class honors degree (or equivalent international degree) in physics, electronic engineering, or a related discipline focused on material and quantum properties.
  • Master's degrees in related fields are preferred and will receive preferential consideration.

Desirable Criteria

  • Experience in quantum optics or related research areas

The annual stipend is €22,000 pa. In addition, yearly University academic fees will be paid by the Tyndall National Institute.

Informal enquiries concerning these positions can be made to Dr. Gediminas Juska (gediminas.juska@tyndall.ie).

The closing date for applications is 30th August, 2024.
