dc.description.abstract
When manipulating quantum systems with electromagnetic radiation, the spatial reso lution is usually constrained by the diffraction limit. To overcome this limitation, we have
developed a fundamentally new approach, in which we attempt to coherently transmit
electromagnetic excitation through the non-radiating near-field of a modulated electron
beam. This could open a path to spectrally selective quantum control with nanoscale
spatial resolution by exploiting the small de Broglie wavelength of electrons. In a proof
of principle experiment we use a spatially modulated electron beam generated by a fast
cathode ray tube from an analog oscilloscope to coherently drive the hyperfine levels of
potassium [1]. To also show coherent manipulation of a solid state quantum system, we
perform Electron Spin Resonance with a BDPA sample. In this experiment realization a
microcoil is used to detect the decay of the excited spins. The deflection of the electron
beam in two dimensions allows for creating painted potentials, e.g. to imitate polarized
light in the microwave range.
