Our research aims at exploring quantum information science at the nanoscale and developing novel quantum photonic devices. Such quantum devices are central for quantum information networks, quantum computation, and quantum cryptography systems, and lie at the basis of a forthcoming Quantum Internet. We focus on quantum control and manipulation of novel nanostructures at the single-photon and single-electron level, using nanowires, quantum dots, and hybrid semiconductor-atomic systems.

This PhD project is focused on experimental investigation and realization of advanced quantum photonic devices, based on photon-phonon coupling in nanowire quantum dots. A semiconductor nanowire with embedded quantum dots represents a highly controllable platform for studying photon-phonon interactions at the nanoscale. Mechanical vibrations in the nanowire can induce a shift in the frequency of the single photons emitted from the quantum dot. In this project, we plan to realize such a system by exploiting GaAs quantum dots controllably grown in AlGaAs nanowires. Our quantum dots will also be frequency-locked to one of the optical transitions of rubidium atoms. We are at the very forefront of international research in this area, and the topic is new, creating ample opportunities for the PhD student to push the state-of-the-art significantly and define new standards in the field.

Our group works in a new state-of-the-art quantum nanophotonics lab and in the national center for nano- and micro-fabrication. We work in tight collaboration with a team of quantum nanophotonics theorists and a team of nanofabrication experts. We have established an effective in-house collaboration that covers all aspects of our research: theory and modeling, sample growth and fabrication, experiments and demonstrations. We have created a dynamic research environment of young and senior scientists aimed at excellent science. We are part of Quantum DTU — the Center for Quantum Technologies at DTU.

This PhD position is part of QUDOT-TECH — the Europian Innovative Training Network “Quantum Dots for Photonic Quantum Information Technologies” — which will engage 15 PhD students in five countries working in close collaboration on optical quantum information technologies.

Responsibilities and tasks
You will find working solutions to major research challenges in an ambitious field of quantum technologies. In particular, you will be:

  • Building advanced optical setups for cutting-edge experiments in quantum photonic technologies,
  • Realizing first nanowire devices for quantum non-demolition measurements of single photons,
  • Exploring the boundary between classical and quantum worlds.

As part of the Danish PhD program, you will follow a number of PhD courses as well as take part in teaching and supervision of students. Furthermore, there will be the opportunity to carry out a longer external research stay. We have close collaborations with numerous internationally leading universities and research organizations.

Candidates should have a two-year master's degree (120 ECTS points) in physics or electrical engineering or a similar degree with an academic level equivalent to a two-year master's degree.

Approval and Enrolment
The scholarship for the PhD degree is subject to academic approval, and the candidate will be enrolled in one of the general degree programs at DTU. For information about our enrolment requirements and the general planning of the PhD study program, please see the DTU PhD Guide.

The assessment of the applicants will be made by Associate Professor Nika Akopian.
