Joao Paulo Sinnecker

Experimental physicist, Full Researcher (Titular III) at the Brazilian Center for Research in Physics (CBPF), where he currently serves as Deputy-Director. He holds a B.Sc. (1988), M.Sc. (1991), and Ph.D. (1995) in Physics from the Gleb Wataghin Institute of Physics, UNICAMP, and completed a Postdoctoral Fellowship at the Institute of Applied Magnetism (Spain, 1998). From 1999 to 2009, he was a faculty member at the Institute of Physics of the Federal University of Rio de Janeiro (UFRJ), also serving in academic coordination roles.His career is focused on Condensed Matter Physics, with emphasis on magnetic materials, nanomagnetism, magnetic nanoparticles, multiferroic systems, and superconducting devices for quantum information. He was Deputy Coordinator of the National Nanoscience and Nanotechnology Laboratory (LabNano), part of the SisNANO strategic network, and currently works at the Quantum Technologies Laboratory (QuantumTec) at CBPF, where he is responsible for the nanofabrication of superconducting quantum devices. He has extensive expertise in lithography (optical and electron-beam), nanolithography, and thin-film growth, applied to the development of magnetic nanostructures and superconducting qubits.He is a member of the Physics and Astronomy Advisory Committee (CA) of the Brazilian National Research Council (CNPq), a CNPq Research Productivity Fellow, and a FAPERJ Cientista do Nosso Estado Fellow. He has supervised 12 graduate students (7 M.Sc. and 5 Ph.D. theses), in addition to undergraduate theses and 19 research initiation projects.Author of 104 peer-reviewed articles in international journals, he has received over 1,600 citations with an h-index of 22 (Web of Science). According to Google Scholar, his record includes 2,240 citations, an h-index of 28, and an i10-index of 59, reflecting the broader impact of his scientific contributions.At QuantumTec, he plays a central role in the development of superconducting quantum devices for quantum computing. His work involves the nanofabrication of Josephson junction-based devices, including SQUIDs, superconducting qubits, and transmons, as well as the numerical simulation of device architectures to optimize geometries and operational parameters. He is also engaged in the low-temperature experimental characterization of these devices, through electrical and magnetic measurements that validate and refine prototypes. This work contributes directly to the effort of building national platforms for quantum computing based on superconducting circuits. (Source: Lattes Curriculum)
