HL 3: Focus Session: Progress in Hybrid Phononic Quantum Technologies I

Monday, March 27, 2023, 09:30–13:00, POT 151

Phonons, the quanta of lattice vibrations, are the fundamental excitations in a crystal and couple to literally any type of excitation in a solid. This universal coupling makes them ideally suited for hybrid quantum architectures which synergistically harness the strengths of its components and at the same time mitigate individual shortcomings. For chip-based hybrid quantum devices, phonons are particularly attractive because they can be routed in integrated circuits with very little dissipation over macroscopic distances in the solid state or confined in small mode volume phononic cavities. Although the research of phonons has a long-lasting history, only recently important breakthroughs were made that will unleash the full potential of acoustic waves in quantum technologies. For example, the rapid progress in the development of surface acoustic wave resonators now allows to generate desired phonon quantum states which promotes the field of quantum acoustics.
