Quantum hardware and computing access
IonQ campus system
FIU announced an agreement for an IonQ Superion 256 trapped-ion quantum computer in September 2026. Campus arrival is expected in late 2027. Prof. Krasnok contributes to research and educational planning through FIU’s quantum committee.
Cloud and GPU computing
Teaching and research use IonQ cloud access, Qiskit, QuTiP, and Python. NVIDIA’s CFQ-Control award provided 32,000 A100 80GB GPU-hours during January–June 2026.
Laboratory development
The QTM research program was established with a $500,000 FIU research and infrastructure start-up package, with separate support for three graduate students over two academic years.
Collaborations with RadiaBeam, Chicago, Argonne, Simon Fraser, and LAPLACE–Toulouse connect the lab’s models with superconducting-resonator and plasma experiments.
