If you have a question about this talk, please contact Emily Heavens. Electron-phonon interaction is often neglected in nanoelectronics, even though the nanostructures are usually embedded in solids with sizable electron-phonon coupling tensors. In this talk I will present a sequence of experiments in GaAs-based heterostructures which demonstrate possible ways of how phonons affect the functionality of nanoelectronic devices. My special focus will be on phonon-mediated interaction effects in quantum dot based qubits including detector backaction and interference in phonon absorption. Finally, I will demonstrate the capability of coupled quantum dot systems as single phonon detectors. related publications: [1] Nature Phys. 8, 522 (2012) [2] Phys. Rev.
