Abstract Scope |
Quantum computing with superconducting qubits faces a formidable challenge: decoherence, which introduces errors to cumulative gate operations. To overcome this hurdle, understanding the intricacies of electronic-photonic heterogeneity arising from interface and boundary imperfections at low energy scales is crucial. Specifically, exploring how this heterogeneity impacts superconducting properties, especially within the terahertz (THz) frequency range, is essential. Our approach involves leveraging THz scattering type scanning near-field optical microscopy (THz-sSNOM) to probe qubit devices non-destructively at the nanoscale. In our study, we've observed distinct features within these components and correlated them with measured coherent times. Additionally, we conduct cryogenic magneto-THz imaging to explore topological edge transport, utilizing our instrument's capabilities under extreme conditions of 2 K temperature and 5 T magnetic field. This endeavor provides crucial insights into our ongoing development aimed at comprehensively studying decoherence effects under real qubit operation conditions. |
