Title: Boosting Superconducting Electronics with the Josephson Effect: Towards Hybrid Quantum Circuits and RF-applications
Abstract: Since its first discovery in the early ‘60s, the Josephson effect has been a powerful tool to study the fundamental physics occurring in conventional and unconventional superconducting materials and the exotic phenomena arising when coupling superconductors with barriers far from simple insulators or metals . However, Josephson junctions are not just a laboratory platform. The research community has already demonstrated that they can enhance the capabilities of superconducting electronics in real-world applications: from highly sensitive magnetometry to quantum metrology and from quantum detection to quantum computation . In this talk, we will specifically focus on the possibility of building a hybrid classical/quantum superconducting platform for high-performance computing by exploiting unconventional Josephson junctions that use ferromagnetic tunnel barriers (tunnel-SFS JJs) [3-7]. Tunnel SFS JJs have the potential of enlarging the capabilities of current state-of-the-art superconducting electronics [8-12]. The high quality of tunnel JJs adds to the chance to tune the magnetization of the ferromagnetic barrier. We show that this allows setting up a convenient playground for novel control, read-out, and memorization mechanisms. A. Barone and G. Paternò, John Wiley & Sons, Inc. 9780471014690 (1982).
