Abstract
The possibility of utilizing highly polarized electron spin of the photo-excited triplet state of organic semiconductors (pentacene molecules) embedded in organic crystals and mesoporous materials by zero-field (ZF) and near zero-field (NZF) pulsed electron paramagnetic resonance (EPR) techniques in a quantum computer will be explored. A simple logic gate, such as CNOT, utilizing such highly polarized electron spins communicating with the surrounding paramagnetic nuclei via hyperfine interaction will be discussed. Major advantages of these approaches are: (1) high electron spin polarization, (2) possible single-molecule detection, (3) orchestrated quantum perturbations can be imposed, and (4) pulsed ZF and NZF EPR techniques can be performed without high magnetic field.
