PhD in Quantum Simulations for Electronic Structure Calculations in Molecules and Materials

University of Amsterdam, Netherlands

Updated: 11 days ago
Deadline: ;

Do you have a passion for computational chemistry and are eager to employ quantum computing methods to study complex chemical systems?

The Computational Science Lab within in the Informatics Institute is offering a PhD position focusing on the design, implementation, and validation of electronic structure calculations on current and forthcoming quantum computing hardware. You will not only design quantum software for such applications, but also test these on quantum emulators and actual quantum computers. For the latter you will collaborate with supercomputer centers in Germany that are currently deploying such systems as accelerators for current (petascale) and future (exascale) supercomputing systems.

The research will be carried out in collaboration with the Computational Chemistry group, embedded in the Van ‘t Hoff Institute for Molecular Sciences (HIMS), of the University of Amsterdam and with the Centre for Computational Science at the University College London.

The offered position will also be linked to QuSoft , the Dutch research center for quantum software & technology.

What are you going to do?

The aims of your project are to:

  • Implement and validate quantum chemical modelling on current and future quantum computing hardware. This may include, but is not limited to, the Variational Quantum Eigensolver (VQE) [1], Dissipative Quantum Eigensolver (DQE) [2], Quantum Imaginary Time Evolution (QITE) [3] and Quantum Phase Estimation (QPE) [4] algorithms. The central question is where does potential advantage lie? Linear-depth ansätze may be implemented efficiently in hardware but do not respect system symmetries and are thus prone to barren-plateaus. On the other hand, ansätze retain correct symmetry while the circuit depth is system-dependent. We seek to locate a ‘sweet-spot’ application domain in near-term quantum computers whereby we might surpass classical capabilities.
  • Develop and implement a hybrid quantum/classical computing environment that embeds the quantum computing of high-level electronic structure model in classical computing of medium-level (DFT) electronic structure model of the environment; for example, one might advance and subsequently apply the projection-based embedding work of Ralli, Williams and Coveney [5]. This is wrapped in a setting that allows for molecular dynamics or Monte Carlo sampling of temporal and/or spatial fluctuations to account for thermal fluctuations and transport processes. The application area includes (bio)catalysis that involves metal-based compounds in a complex fluctuating environment such as proteins or solvents.

    • The software implementation will build on existing packages such as Qiskit Nature and Symmer for quantum computing of high-precision electronic structure models and the CP2K code for molecular dynamics/Monte Carlo sampling of DFT-based models.
