AJ Rasmusson - Assistant Professor, BYU Physics and Astronomy

AJ Rasmusson joined the BYU Department of Physics and Astronomy in 2025. Broadly, his research interests push frontiers in quantum computing, simulation, sensing, and networking. His current focus is in the bosonic quantum motional states of trapped-ion systems for quantum error correction, quantum sensing, and next-generation performance of trapped-ion quantum systems.

He worked with trapped-ion qubits in his graduate studies at Indiana University to realize 2D ion crystals, faster laser cooling protocols, and chemical simulations on trapped-ion quantum computers. While a graduate student, AJ joined the IBM Quantum team to develop the IBM Quantum Open Science Prize and contributed to open science efforts. After graduate school, AJ joined the Ion Storage group at the National Institute of Standards and Technology (NIST) in Boulder, CO as an NRC postdoctoral fellow. He worked on realizing new techniques with trapped-ion quantum motional states for quantum error correction applications. He and his family enjoy biking, reading, 3D printing, baking, laughing, and eating sushi and ice cream (but not at the same time).
