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
