The first cuprate-based twisted high-temperature superconducting heterostructures in Europe were developed in the Superpuddles Lab. Since 2024, the first lab of this kind in Italy has been in development at the University of Naples “Federico II.“. The newly established lab actively contributes to intra-European collaborative research, building on the original Superpuddles Lab founded in 2019 at the Leibniz Institute for Solid State and Materials Research (IFW) in Dresden, Germany. The practical synergy between the two labs is sustained through joint research projects, and student exchange programs, combining expertise in superconducting quantum materials and superconducting quantum technologies, supporting steady progress toward real-world applications in quantum computing and communications.

A new research direction has emerged in the engineering of correlated topological phases, driven by a revolution in materials science centered on two-dimensional (2D) materials. Known as “twistronics” or Moiré materials, this approach involves stacking 2D materials with a defined interlayer twist to generate novel electronic properties. Within the broader context of the second quantum revolution—which encompasses quantum sensing and quantum computing—twistronic systems offer substantial potential. Their high tunability, particularly in the configuration of Josephson junctions, allows for controlled manipulation of the macroscopic wave function of the condensate and enables efficient integration of these devices into complex quantum circuits.

Our group focuses on advancing superconducting quantum materials through three primary research directions: fundamental science, measurement techniques, and the development of quantum technologies. We explore topological superconducting phases, develop fabrication strategies for twisted architectures based on two-dimensional complex oxides and other 2D superconductors, and design large- scale circuit architectures for future quantum applications.
