PhD

The Quantum Information Group (GIQ) of the Universitat Autònoma de Barcelona, UAB, offers a PhD position (up to 4 years) within the project DyRQI (Dynamical Resources in Quantum Information) funded by the Ministerio de Ciencia e Innovación, ref .PID2019-107609GB-I00.
We seek promising PhD candidates and offer a stimulating environment to pursue research projects oriented along two possible research tracks: A) Advanced inference methods: quantum sequential analysis and quantum learning. B) Quantum thermodynamics, open quantum systems and resource theories.

Applications are open for Government of Ireland PhD scholarships, beginning fall 2021. The deadline for applications is October 29, 2020. I would be interested in supporting applications from strong candidates for research in Quantum walks or Quantum games at the National University of Ireland Galway. For initial discussions, please email me at michael.mcgettrick@nuigalway.ie.

PhD and Postdoc positions (3 years) are available in the newly established Quantum Error Correction group led by Felix Huber at the Jagiellonian University in Krakow.

We are looking for exceptional candidates with background in quantum information or mathematics, with an interest in theoretical or experimental quantum error correction, entanglement theory, optimization, invariant theory, and/or mathematical physics.

BASF SE offers a temporary PhD position from 01.01.2021 that aims at developing workflows for molecular quantum-chemistry applications on quantum computers. In the position, scientific work will be performed at the Ludwigshafen site. Your contract will be with BASF SE as the employer. Co-supervision will take place with the University of Erlangen-Nuremberg.

We are offering a postdoc (E13) and a PhD position (E13 3/4) to highly motivated and well-qualified researchers who intend to conduct research in near-term quantum computing and simulation. Possible topics include the following:

- Notions of quantum machine learning and near-term quantum computing

- Benchmarking and tomography

- Analog quantum simulation

- Computational complexity theory

The successful candidates will work as part of the research group led by Jens Eisert at the FU Berlin. For an overview of research activities, see

This position is embedded in the research project QUANTUS‐IV MAIUS, which is carried out by the QUANTUS collaboration of seven German Universities and Research Institutes. QUANTUS (“Quanten‐gase unter Schwerelosigkeit”) is funded by the German Aerospace Center (DLR) and aims to investigate ultra‐cold quantum gases in microgravity.

Solid-state spins in an optical cavity

The ultimate goal is to create spin-spin entanglements at useful rates. A number of challenges have to be overcome. The materials processing must be improved in order to create optically-coherent NV centres in thin diamond-membranes. Quantum optics-based techniques must be used to quantify the properties of the photons: their purity and indistinguishability. Spin manipulation must be combined with the cavity setup. Techniques must be established to tune remote NV centres into resonance with each other. The project will offer experience in all these fields, along with possibilities to explore the application of the same cavity structure to other solid-state systems, for instance semiconductor quantum dots.

Hybrid quantum networks with atomic memories and quantum dot single-photon sources

The goal of this project is to interface the two systems through an optical fiber link that was recently installed in Basel. Several improvements will be implemented to achieve low-noise operation: controlling the charge state of the dot and enhancing the photon collection efficiency with an optical cavity, as well as controlling the spin state of the atoms to suppress four-wave mixing noise by selection rules. After demonstrating storage and retrieval of quantum dot single photons in the atomic memory, we intend to perform basic quantum networking tasks such as entangling two remote atomic memories.

Experimental Quantum Simulations based on Trapped Ions (& Atoms)

Direct experimental access to the most intriguing and puzzling quantum phenomena is extremely difficult and their numerical simulation on conventional computers can easily become computationally intractable. However, one might gain deeper insight into complex quantum dynamics via experimentally simulating and modelling the quantum behaviour of interest in a second quantum system. There, the significant parameters and interactions are precisely controlled and underlying quantum effects can be detected sufficiently well, thus, their relevance might be revealed. Trapped atomic ions have been shown to be a unique platform for quantum control, evidenced by the most precise operations of quantum information processing and their performance as best atomic clocks. Still, scaling is the major challenge – i.e. the endeavour to control increasingly large systems of particles at the quantum level will be one of the driving forces for physical sciences in the coming decades. We aim to control charged atoms at the highest level possible to further scale many-body (model) systems ion by ion. This approach is, in a way, the ultimate form of engineering - in radio-frequency traps, as well as in all-optical traps, when combined with ultracold atoms.
