Shaped pulses enable robust coherent control of quantum dots: perspectives for quantum technologies — •Vikas Remesh — Institute für Experimentalphysik, Universität Innsbruck, Innsbruck, Austria

Shaped laser pulses have been remarkably effective in investigating and controlling various light-matter interactions in a broad area of research. In quantum technologies, the techniques to shape complex spatiotemporal waveforms have found renewed interest, for instance in coherent control of quantum dots [1]. In this talk, I will navigate through the impact of pulse shaping techniques in nanospectroscopy and how it enabled efficient preparation schemes in quantum dots, based on our recent works [2], including the pioneering off-resonant coherent control of quantum dots, compact plug-and-play method of exciting multiple quantum dots and accessing dark excitons in quantum dots for advanced entanglement generation. Afterwards, I will conclude with my vision on the future scope of nanophotonics-assisted-quantum technology roadmap.
