Institute issuing the offer: INM-9

Your Job:

The overarching goal is to implement a code for multiscale quantum mechanics / molecular mechanics (QM/MM) molecular dynamics simulations using a Quantum Centric Supercomputing (QSC) approach [1,2] for the QM problem. This will be integrated within the in-house MiMiC framework [3] and applied to study proton transport in H+-coupled transporters. The project will be carried out in collaboration with a team of experts at FZJ (INM-9: Institute of Neuroscience and Medicine - Computational Biomedicine, IBI-1: Institute of Biological Information Processing - Molecular and Cellular Physiology; JSC: Jülich Supercomputing Centre) and from the US (IBM Research and Michigan State University).

Specific tasks include:

• Implement the classical components of the Sample-Based Quantum Diagonalization [1] method within the MiMiC multiscale simulation framework
• Develop and integrate a communication interface between quantum computers (via Qiskit) and classical HPC resources
• Validate the QCS-MiMiC implementation on IBM’s ibm_cleveland quantum computer by reproducing recently published benchmark QM/MM simulations [2]
• Apply the developed code to simulate proton transport in vesicular glutamate transporters
• Collaborate closely with an interdisciplinary team across quantum computing, molecular simulation, and neurobiology
• Participation in conferences in Germany and abroad (incl. presenting your research results)
• Exchange with internal and external as well as national and international project partners
• Preparing scientific publications and project reports

Your Profile:

• University degree (Master) in Physics, Chemistry, Computer Science, or related fields, with an overall grade of at least “gut” (or equivalent, e.g. cum laude)
• Expertise in quantum mechanics; Experience with HPC, programming (e.g., Python, C/C++), and/or scientific computing is a plus
• Strong interest in quantum computing and molecular simulations
• Willingness to work in an interdisciplinary, international team
• Fluent command of written and spoken English
• High degree of independence and commitment
• Very reliable and conscientious style of working
