QTM Lab
Quantum Technologies and Metamaterials Lab
QTM Lab engineers waveform- and metamaterial-enabled electromagnetic systems for quantum hardware, precision sensing, and photonic control. We combine complex-frequency electrodynamics, cryogenic quantum interfaces, metasurfaces, and reproducible computation to move ideas from wave physics to deployable devices.
