Scattering-type scanning near-field optical microscopy (s-SNOM) and nanoscale infrared point spectroscopy (nano-FTIR) are powerful techniques for nanoscale optical mapping of various material properties. Both rely on elastic light scattering from an atomic force microscope tip illuminated by either monochromatic or broadband laser light. This metallic tip acts as an optical antenna,...
Hybrid superconductor-semiconductor devices are of interest for various applications in quantum physics – they can host different types of qubits or can be used for compact, low-noise, cryogenic electronics elements such as parametric amplifiers [1]. As semiconductor, we employ strained germanium quantum wells embedded in planar silicon-germanium heterostructures. Germanium was shown to be a...
Rare-earth ions exhibit exceptional magnetic and optical properties, making them attractive systems for applications in quantum information science. While significant progress has been achieved in the storage of optical quantum states, the direct storage and coherent manipulation of microwave quantum states remains an important open challenge.
Here, we investigate broadband control of...
