Localized orbital electronic states of colour centres in diamond for strong and fast light-matter interactions

Christian Weinzetl, Jonas N. Becker, Johannes Görlitz +7 more

For memory applications and optical control of qubits ultrafast manipulation and high coupling efficiencies are desirable. Ultrafast coherent control can be achieved by the off-resonant Raman scheme [1]. There exist several colour centres with an optically accessible lambda-type energy structure which offer a level splitting large enough for broadband laser pulses.

Ultrafast all-optical coherent control of silicon vacancy colour centres in diamond

Jonas N. Becker, Johannes Görlitz, Carsten Arend +5 more

Full coherent control of quantum systems is a key prerequisite to build a quantum information processing (QIP) system. Spatially selective and ultrafast control of individual qubits in multi-qubit systems, on the other hand, optimally is based on all-optical control techniques using short laser pulses. However, these techniques require optically accessible quantum systems with suitable electronic level configurations to allow for the application of ultrafast and thus broadband pulses. Moreover, to enable good scalability, quantum systems in the solid state are generally preferred. So far, the only quantum systems in the solid state that match all these requirements are semiconductor quantum dots. However, to achieve a suitable level structure in these systems charged dots in strong magnetic fields have to be used.Full coherent control of quantum systems is a key prerequisite to build a quantum information processing (QIP) system.

Electron modulation and ultrafast near-field imaging with vectorial laser fields

J. Kuttruff, L. Möhrle, L. Ciorciaro +2 more

Controlled interaction of laser light with electron beams is fundamental for ultrafast electron microscopy and electron-based quantum optics, yet their direct coupling is forbidden in free space. Here we use longitudinally polarized light at a thin membrane and show that the emerging focal fields can modulate the electron beam in a direct, coherent and linear way, without the need for nanostructured materials or slanted interaction geometries. Also, we use vectorial polarizations to excite and probe three-dimensional nanophotonic near-fields in metallic mesocrystals by coherent electron energy gain and loss. We find that longitudinal electric fields excite axial near-fields in a direct way while longitudinal magnetic fields excite oscillating ring currents via azimuthal electric fields. These possibilities enable tilt-free, collinear generation of attosecond electron pulses or free-electron qubits and provide novel imaging modes in ultrafast electron microscopy and metamaterial tomography.Controlled interaction of laser light with electron beams is fundamental for ultrafast electron microscopy and electron-based quantum optics, yet their direct coupling is forbidden in free space.
