"IR irradiated molecules vibrate due to energy supply, also generating magnetic fields... highly symmetric metal phthalocyanines generate nm magnetic fields when circularly polarized IR pulsed on their charged atomic nuclei, exciting 2 molecular vibrations at same time at right angles to each other... high-precision optical switches controlling magnetic field strength, direction... future: compute interactions between deposited phthalocyanines, support material, IR... circuits in quantum computers"
