This talk presents ongoing research activities at IUAC related to ion traps, fundamental physics, and quantum computing. The first part focuses on electron impact ionization cross-section studies using the 1-8 MeV electron beam from the IUAC FEL facility to investigate high-energy electron-ion interactions. The second part discusses Penning trap experiments aimed at measurement of zero-point energy and the development of trapped-electron quantum computing using planar Penning traps. The talk will also highlight activities at Qute Electronics, a spin-off of IUAC, related to the development of precision ultra-low-noise power supplies, RF generators, HEMT amplifiers, and other precision electronic for quantum computing and precision experiments.
