The Quantum Thermodynamics Group in the Department of Physics at UMBC invites applications for a Postdoctoral Research Associate to work under the mentorship of Dr. Sebastian Deffner. This postdoctoral position will be funded by a grant from the U.S. Department of Energy.

The postdoc will conduct theoretical research on quantum information scrambling and its relevance to molecular memories. We are witnessing a global race to develop the first fault-tolerant quantum computers that can handle applications at realistic scales. To date, several architectures for quantum hardware have been developed that all have their strengths and weaknesses. For instance, ion trap based computers have a high degree of controllability and are only weakly susceptible to noise, yet with only tens of qubits they are comparatively small. Superconducting technologies have already achieved thousands of qubits, but their chip-design is prone to noise. Another potential platform for quantum computing is based on molecular systems. Generally, quantum computing relies on the precise control of quantum information in complex systems, yet the fundamental processes that govern how information spreads, scrambles, or becomes inaccessible remain poorly understood. In particular, molecules offer a tunable and naturally complex platform for studying these phenomena, making them ideal systems for uncovering the principles behind quantum information flow and control. A major open question is how chaotic dispersion of quantum information emerges in molecular systems and how this transition relates to the loss or protection of quantum information. Without a detailed understanding of these processes, it remains difficult to design quantum systems that are both powerful and secure. The postdoctoral research will contribute to uncovering the conditions under which quantum information becomes scrambled in molecules, and in determining the minimal complexity needed for these systems to serve as secure quantum memories or components in quantum computing.

The start date is expected to at the beginning of Spring Semester 2026, i.e., February 2026. The initial appointment is for one year, but renewal for up to 2 years is anticipated, subject to performance and funding. Candidates should have a PhD in Theoretical Physics, and a proven track record in quantum chaos, quantum information scrambling, open quantum dynamics, and/or quantum decoherence. The Quantum Thermodynamics Group is highly active, with 3-4 graduate students and 4-5 undergraduate researchers at any given time. Candidates with an interest in teaching and mentoring will be provided with opportunities to further their experience where feasible.

UMBC and the Department of Physics are dedicated to creating an inclusive, collegial environment where all faculty members can achieve excellence. Thus, candidates from diverse backgrounds, including women and under-represented minorities, are particularly encouraged to apply. Interest and experience in working with a diverse student and faculty population is valued. The Department of Physics has an active Graduate Women in Physics group and an Undergraduate Women and Gender Minorities in Physics group, and has ties with the nationally acclaimed Meyerhoff Scholars Program. UMBC is an affirmative action/equal opportunity employer.

Candidates should have a PhD in Theoretical Physics, and a proven track record in quantum chaos, quantum information scrambling, open quantum dynamics, and/or quantum decoherence.
