Franklin H Cho
During Ph.D. at the University of Southern California (USC), Franklin participated in the development of a custom continues-wave (cw)/pulsed high-frequency/-field electron paramagentic resonance (EPR) spectrometer operating at 230/110 GHz with electron-electron double resonance (ELDOR) and dynamical decoupling (DD) capability. And with the spectrometer, he mainly studied ensemble of paramagnetic defects and radicals in solid samples, mostly synthetic diamond crystals.
Then Franklin Cho moved to the Institute for Quantum Computing (IQC), University of Waterloo (UW), where he worked as a postdoctoral researcher on experimentally realizing various gradient-based, open-/closed-loop quantum optimal control methods in electron-nuclear coupled systems using a custom pulsed X-band EPR/electron-nuclear double resonance (ENDOR) spectrometer with arbitrary waveform generator (AWG) capability.
