Job Summary

POST-DOCTORAL RESEARCH POSITION IN THE NANOMATERIALS AND SPECTROSCOPY GROUP
Plexcitonic quantum nanostructures as a source of entangled photons for practical
photonic quantum technology hardware

Job Description

The rapidly advancing field of photonic quantum technologies brings significant
opportunities in quantum cryptography, quantum modelling and computing, metrology,
sensing, spectroscopy and imaging, all with unprecedented capabilities. Entangled photons
are an indispensable tool for the development of all these applications and an essential
resource in quantum optics experiments. Ensuring stable, reliable and spectrally pure
generation of the entangled photonic states on-demand has been a tremendous scientific
challenge in recent years. Currently, semiconductor quantum dots (QDs) are extremely
promising quantum emitters capable of generating biexciton states. Radiative biexciton exciton recombination cascade can ultimately lead to the emission of two entangled
photons. It is a very attractive resource for quantum information processing since it
potentially allows for the simplification of quantum circuit designs due to a reduced number
of entangling gates. However, utilising the full potential of quantum dots as two-photon
quantum emitters is hampered by the limitations related to emission-signal instability and
the low biexciton quantum yield. Nanoscale plasmon-exciton coupling can significantly
stabilise and improve the emission properties of quantum dots by producing hybrid plasmon exciton (plexciton) states that serve as quantum emitters, thereby overcoming the
constraints above.
The main goal of the project is to experimentally implement high-performance nanoscale
plexciton quantum emitters operating as on-demand sources of pure pairs of entangled
photons.
To achieve this goal, the following objectives must be fulfilled: (1) to design QEs based on
the QDs and plasmon nanostructures with implemented synergistic combination of plasmon induces effects; (2) to develop new approaches and methods to control different regimes of
plasmon-exciton interaction in the designed structures; (3) to optimize the conditions of light matter coupling to achieve the highest values of the generation efficiency, single-photon
purity, and entanglement fidelity for the photon-pair mode.
The project is essentially experimental, but is combined with theoretical simulations. This
includes the combination of nanomaterial preparation and processing techniques, optical
spectroscopy at the single quantum dot level, single photons manipulation and the use of
advanced computational modeling.
The candidate is expected to have PhD in Physics (preferably Laser Optics), Materials
Science, Nanoscience or Photonics. Previous experience is preferred in one or more of
the following areas: plasmonics, optics, luminescent nanocrystals, quantum dots, optical
spectroscopy, photon correlation spectroscopy. Good written and oral communication
skills in English are mandatory.
