Job description

We are seeking a postdoctoral researcher to work at the intersection of tensor networks, quantum algorithms, scientific computing, topological physics, and quantum hardware. As part of our team, you will perform research to develop new scalable quantum simulation algorithms, based on multi-linear representation theory, and apply them to real world applications spanning qubit engineering to quantum algorithmic analysis to applications across the physical sciences (condensed‑matter or high energy physics, data science). You will Interpret, report, and present research concepts and results to national audiences.

Major Duties/Responsibilities

• Conduct research in mathematical representations of quantum states and processes, develop algorithms, and produce open-source scientific software
• Write peer-reviewed scientific articles and present research findings at major scientific conferences
• Collaborate with ORNL staff scientists and external collaborators
• Deliver ORNL’s mission by aligning behaviors, priorities, and interactions with our core values of Impact, Integrity, Teamwork, Safety, and Service

Basic Qualifications

• A Ph.D. degree in Mathematics, Computer Science, Physics, Chemistry, Engineering, or a related discipline.
• A strong foundation in linear algebra (tensor networks and beyond) and quantum physics
• Familiar with programming languages and scientific computing

Preferred Qualifications

• Experience working with low‑rank linear algebraic approximation methods.
• Experience with quantum algorithms (other than variational or adiabatic) and/or quantum hardware
• Knowledge of topological quantum field theories, topological band theory.
• Strong analytic mathematical skills.
• Experience in multiple scientific programming languages (Python, Julia, Fortran, C++, AI etc.)
• Excellent written and oral communication skills.
• Motivated self‑starter with the ability to work independently and to participate creatively in collaborative teams across the laboratory.
• Ability to function well in a fast‑paced research environment, set priorities to accomplish multiple tasks within deadlines, and adapt to ever changing needs.
