Post-doctoral Researcher for Quantum Open Systems group, ICTQT, UG

Updated: about 2 months ago
Job Type: FullTime
Deadline: 22 Jan 2021

We are looking for the post-doctoral researcher to work in the newly created International Centre for Theory of Quantum Technologies (ICTQT), funded by the Foundation for Polish Science, and hosted by the University of Gdansk. The founders of ICTQT are Marek Zukowski as the director and Pawel Horodecki as a co-applicant. The Centre’s official foreign partner is IQOQI-Vienna of the Austrian Academy of Sciences. Gdansk is the pioneering and leading centre of quantum information research in Poland. Gdansk and the whole Tri-City is one of the most beautifully located urban areas in Poland, with sandy sea beaches, lakes, and woods within in it and in the nearby area. It is the birthplace of Polish jazz and rock festivals, and vibrant in many fields.

About the research group

The broad aim of the Quantum Open Systems in Relation to Quantum Optics Group is to build up understanding of the (quantum) thermodynamic properties of laser beams. The research will focus on analogies between open system dynamics and transmission of optical beams, and the thermodynamic context of indefinite causal order implemented in interferometric setups. Additionally, the group will study gate set tomography and quantum random walks, as well as will coordinate the QuantERA project ApresSF – Application-ready superresolution in space and frequency – devoted to quantum metrology and light.

Specific goals of the group include:

–         To study macroscopic models of evolution for laser beams, with special emphasis put on polarization, orbital angular momentum and spatial degrees of freedom.

–         To study the thermodynamic characterization of the optical beams.

–         To reconsider known quantum thermodynamic models by adding the feature of indefinite causal order.

–         To optimize metrological protocols leading to superresolution in spatial, spectral and temporal separation measurements.

–          To improve the protocol of gate set tomography with regards to its intrinsic symmetries (so-called gauge).

About the “Application-ready superresolution in space and frequency“ project

For the resolution of two sub-Rayleigh sources, such as stars or microscopic fluorophores, novel methods have very recently been theoretically and experimentally shown to outperform direct imaging, reaching the true quantum limits. Further efforts to generalize the theory for arbitrary sources suggest that, despite the existence of harsh quantum limits, the quantum-inspired methods can still offer significant improvements over direct imaging, potentially rendering more applications in astronomy, as well as in fluorescence microscopy. Such protocols for quantumenhanced parameter estimation can also be applied to measure time or frequency with very high accuracy.

The goal of the post-doctoral researchers will be to use expertise from the field of quantum optics and quantum information in order to advance on the research problems delineated in this description.

Keywords: quantum metrology, superresolution, quantum optics, quantum information.

The positions of a post-doctoral researcher offered by the International Centre for Theory of Quantum Technologies of the University of Gdansk is within the implementation of the project “Application-ready superresolution in space and frequency”. The project is financed by the National Science Centre (Poland) from the funds of the QuantERA ERA-NET Cofund in Quantum Technologies programme supported by the European Union’s Future and Emerging Technologies programme (FET).

QuantERA is a network of 32 organisations from 27 countries, coordinated by the National Science Centre, Poland, supporting international research projects in the field of Quantum Technologies (QT). QuantERA answers the growing need for collaborative endeavours and common funding scheme within QT research, which due to its highly interdisciplinary nature cannot be confined to an individual institution or state. Through coordination of national and regional research funding programmes QuantERA avoids the problem of fragmentation of national efforts, encouraging transnational collaborations and leveraging Europe’s competitive advantage. Join call for proposals for international research groups operating in QuantERA partner countries will become the first step to further integration.

Key responsibilities include

  • Active scientific research.

  • Presentation of project results to internal and external parties.

  • Active procurement of new research grants from external sources.

  • Participation in mentoring of PhD and Master students.

  • Participation in the organizational activity of ICTQT. 

  • Active involvement in seminars, group meetings, etc.
