Postdoctoral Fellow in Quantum Simulation and Bosonic Quantum Information

Your tasks ##

The position concerns theoretical research at the interface of quantum information theory and quantum many-body physics, with applications to quantum simulation and quantum computing. Particular focus is placed on bosonic and hybrid qubit-boson systems and applications to quantum chemistry. Possible research directions include developing resource-efficient quantum simulation methods, designing quantum learning and benchmarking protocols, and characterizing the capabilities and limitations of realistic quantum computing devices. 

The position is embedded in the interdisciplinary Quantum Molecular Dynamics project, a collaboration between PSI and ETH Zurich. The project aims to develop and benchmark quantum simulation methods for challenging problems in molecular quantum dynamics, with a particular focus on mixed-qudit-boson approaches. It brings together expertise in quantum information theory and theoretical chemistry with experimental quantum computing platforms based on trapped ions and superconducting quantum circuits. The position offers opportunities for close collaboration with experimental and theoretical partners at PSI and ETH Zurich.

Your tasks will include:

• Conduct research in quantum information theory and quantum many-body physics, with applications to quantum simulation and quantum computing 
• Develop theoretical methods for quantum simulation, learning and benchmarking, particularly for bosonic and hybrid quantum systems, with applications to quantum chemistry and molecular dynamics 
• Collaborate closely with experimental quantum computing groups at PSI and theoretical partners within the project 
• Publish research results in peer-reviewed journals and present findings at international conferences

Your profile ##

• PhD degree in Physics or a closely related field 
• Strong research background in quantum information theory, quantum many-body physics, quantum simulation or related areas 
• Experience in bosonic or continuous-variable quantum information, quantum learning and benchmarking or quantum chemistry would be particularly welcome 
• Motivated, collaborative and able to work effectively both independently and in a team environment 
• Experience in analytical or numerical research methods, including scientific programming 
• Good knowledge of English
