Superconducting Electronics: Transparent Samples and SQUID-like Josephson Junctions

Explore the latest advancements in superconducting electronics with a focus on transparent samples and SQUID-like Josephson junctions in this 45-minute conference talk from the HyperComplex Seminar 2023. Delve into the methodological approach for developing superconductors with acceptable transparency and high critical temperatures, examining the complex interplay between free carrier absorption and interband transitions. Discover how these factors contribute to the coexistence of high carrier density at the Fermi level and transparency for visible light. Learn about the successes achieved using electrochemically doped indium-tin-oxide compounds as a reference material for testing new ideas in transparent superconductors. Gain insights into the potential applications of these advancements in quantum computing, communications, and sensing, particularly in interfacing stationary superconducting qubits with flying photonic qubits for improved quantum information transmission.
