Postdoctoral research position in Chemical simulations based on Quantum Computing
Are you a highly-motivated postdoctoral researcher with excellent skills for performing Chemical simulations based on Quantum Computing? Then you could be the candidate we are looking for.
We have a two year postdoctoral position available in a joint research initiative (started by TOYOTA, QuSoft, UvA and VU) that is aimed at exploring potential usage of quantum computing for research and development. You will be employed at the Institute of Physics (IoP) of the University of Amsterdam (UvA). The main research environments will be the QuSoft Center (housed by CWI) and the Theoretical Chemistry group at the Vrije Universiteit (VU).
What are you going to do?
Focus of the project will be the study of photocatalytic systems on quantum computers. Stationary molecules or chemical reactions pertaining to heterogenous photocatalysis systems will be analyzed with the help of quantum computing and quantum simulation techniques. The goal is to identify pathways from exploratory simulations on simulators or NISQ type devices towards the goal of accurate calculations on realistic model systems. Important aspect of the project is algorithmic development: case-specific improving, tweaking and optimizing of approaches, such as those based on a Variational Quantum Eigensolver (VQE) or on Hamiltonian simulation in combination with Quantum Phase Estimation (QPE).
The project will be supervised by:
- dr Sachin Kinge for TOYOTA
- prof Kareljan Schoutens for QuSoft, UvA
- prof Lucas Visscher for VU
The results of the research will be published in the open literature. At the same time, the results will be shared within the collaboration through regular updates, progress meetings and internal reports.
What do we require?
The successful candidate should have:
- a completed PhD in (Computational) Chemistry, Theoretical Physics or Computer Science;
- expertise in and affinity for computational approaches to chemistry, materials or condensed matter systems;
- strong motivation to work in a cross-disciplinary environment at the interface of academic and corporate research.
We offer a two-year contract for 38 hours a week, preferably starting on 1 June or 1 July 2021.
The salary, depending on relevant experience before the beginning of the employment contract, will be €2,790 to €4,402 (scale 10) gross per month, based on a fulltime contract (38 hours a week). This is exclusive 8% holiday allowance and 8.3% end-of-year bonus. A favourable tax agreement, the ‘30% ruling’, may apply to non-Dutch applicants. The Collective Labour Agreement of Dutch Universities is applicable.

Project 1: Testing quantum measurements
Quantum entanglement is a phenomenon where separate quantum systems form mysterious connections that can be observed when these systems are measured locally [Chapter 16, de Wolf]. The presence and even the strength of entanglement can be gauged using particular sequences of local measurements. This project is about developing tests to determine if the right kind of measurements were performed by looking only at the observed measurement outcomes. This will involve proving non-commutative analogs of the Gowers Inverse Theorem from additive combinatorics [Lecture 2, Green], [Westdorp]. As such, this project brings together ideas from quantum information theory, discrete mathematics and representation theory.

Project 2: Quantum query complexity
A proxy for time-complexity of an algorithm is the number of bits of the input it reads in the worst-case, the so-called query complexity. Quantum algorithms can query input strings in superposition [Chapter 11, de Wolf], which can sometimes lead to much faster algorithms such as Shor’s algorithm for integer factorization. Understanding quantum query complexity is one of the major challenges of quantum computing. This project is about exploiting a recently-discovered characterization of quantum query complexity in terms of polynomials [Arunachalam et al.]. Fourier analysis of boolean functions [O’Donnell] and the theory of semidefinite programming [Gribling & Laurent] (a generalization of linear programming) have given powerful tools to study crude bounds on quantum query complexity in terms of polynomials. In this project, these tools will be sharpened using analytic and operator-space theoretic techniques.

PhD position on the theory of quantum networks
While a quantum internet is being developed, many open questions remain on the power of networked quantum computers: What are their exact capabilities? And for which distributed tasks can new protocols be found?
The MNS group of the Informatics Institute invites you to apply for a PhD position working on these questions.
What are you going to do?
As part of your PhD project, you will develop new multiparty protocols for joint computational tasks on quantum networks, and prove limits on their power. Research directions for your PhD include:
- Joint quantum computation under timing constraints. What if networked quantum computers have to perform a computational task together, but are only allowed limited rounds of communication? Can there be a trade-off between time taken and entanglement?
- Computing on encrypted quantum data. In a quantum network, multiple parties will have to handle quantum data, while not completely trusting each other. To handle this situation, research will have to advance the state-of-the-art in secure quantum computation.
- You will be embedded in the MNS group of the Institute of Informatics of the University of Amsterdam. The group focuses its research on the fundamental architectural problems that arise from the interconnection of systems and of data flows. We look at the emerging architectures that can support the operations of the future Internet.
- You will work under the supervision of dr Florian Speelman, who will also serve as your co-promotor, and of dr Paola Grosso as promotor.
- You will also work in close collaboration with QuSoft, the Dutch research institute for quantum software, which houses experts on all topics in quantum computing. Together, the local institutes form a rich research ecosystem with opportunities to work together with computer scientists, physicists and mathematicians from the various groups situated at the Amsterdam Science Park.
- You will start your PhD project concurrently with a PhD student who will work on theoretical questions directly associated with the Quantum Delta CAT-2 project. This gives the opportunity to work together on shared research questions concerning applications on the prototype quantum network that is being developed.
All applications received before April 1, 2021 will receive full consideration. For more information, and to apply, click here.
