Terahertz radiation has become an important diagnostic tool in the development of new
technologies. However, the diffraction limit prevents terahertz radiation (λ≈ 0.01–3 mm) …

Amorphous solids show surprisingly universal behaviour at low temperatures. The
prevailing wisdom is that this can be explained by the existence of two-state defects within …

The focused ion beam (FIB) is a powerful tool for fabrication, modification, and
characterization of materials down to the nanoscale. Starting with the gallium FIB, which was …

A major issue for the implementation of large-scale superconducting quantum circuits is the
interaction with interfacial two-level system (TLS) defects that lead to qubit parameter …

We present fast tunable superconducting microwave resonators fabricated from planar Nb N
on a sapphire substrate. The 3 λ/4 wavelength resonators are tuning fork shaped and tuned …

Understanding the nanoscale electrodynamic properties of a material at microwave
frequencies is of great interest for materials science, condensed matter physics, device …

Advanced microwave technologies constitute the foundation of a wide range of modern
sciences, including microwave integrated circuits, quantum computing, microwave …

Quantum circuits show unprecedented sensitivity to external fluctuations compared to their
classical counterparts, and it can take as little as a single atomic defect somewhere in a mm …

Low-temperature scanning probe microscopes (SPMs) are critical for the study of quantum
materials and quantum information science. Due to the rising costs of helium, cryogen-free …

Microwave impedance microscopy (MIM) is a near-field imaging technique that has been
used to visualize the local conductivity of materials with nanoscale resolution across the …
