Title
Quantum Microscopy at Ultra-Low Temperatures: Exploring the Hidden Landscape of Quantum Devices
Abstract
Advances in quantum sensing are transforming our ability to probe the nanoscale properties of materials and devices. Milli-Kelvin Scanning Probe Microscopy (mK-SPM) enables non-invasive, high-resolution imaging of electronic, magnetic, and charge landscapes in operational quantum devices, providing critical insights into performance-limiting factors such as charge disorder, nanomagnet field profiles, and TLS defects in superconducting circuits.
This talk will introduce the principles behind mK-SPM and illustrate how advanced technologies 鈥� including cryo-walking nanopositioners and in-situ cryogenic vibration isolation 鈥� allow stable, precise operation at ultra-low temperatures. I will highlight examples of how these techniques reveal previously inaccessible phenomena, enable feedback for device optimization, and accelerate the development of quantum sensors and quantum computing components. By bridging fundamental physics with cutting-edge instrumentation, quantum microscopy is opening new avenues for both applied technology and quantum metrology.
