Akira Fujimaki received his B.E., M.E., and Dr. Eng. Degrees from Tohoku University in 1982, 1984, and 1987, respectively. He was a Visiting Assistant Research Engineer at the University of California, Berkeley, in 1987. Since 1988, he has been working at the Graduate School of Engineering, Nagoya University, Japan, where he is currently a professor. Since 2019, he has also been a vice president of Nagoya University. He has been working on superconducting digital electronics since 1981. He observed various dynamic behaviors of fluxons in Josephson junctions. He also demonstrated the single flux quantum circuits by using Nb-based Josephson junctions, and high-temperature-superconductor-based junctions. The circuits are applied to the software-defined radio receivers, the detector systems. Currently his research focuses on high-performance computers. His group developed the integration technology of p-phase-shifted magnetic Josephson junctions. Based on those, he has been tackling to develop energy-efficient logic circuit, matrix memories, and quantum annealing circuits.
|Gregory Goltsman obtained his Ph.D. degree in Physics of Semiconductors from Moscow State Pedagogical University in 1973. Currently, he holds the position of professor and chair of the Division of Quantum Optics and Telecommunication at Moscow Institute of Electronics, Mathematics, and Higher School of Economics. He is a pioneering physicist. His past achievements include: the first observation of optical transitions between energy levels of excitons in monocrystalline semiconductors; the discovery of the negatively charged state of shallow donors and the positively charged state of shallow acceptors in monocrystalline semiconductors; the study of electronic energy relaxation in disordered films of superconductors; the discovery and promotion of the superconducting hot electron bolometric mixer and the superconducting single-photon detector. He has won several prizes, including the stipend from the Soros Foundation for Professors (1996-2001), the IEEE Van Duzer Prize in Applied Superconductivity (2010), and the IEEE Award for Continuing and Significant Contributions in the Field of Applied Superconductivity (2017). In 2005, He founded a start-up company called Scontel, which produces ready-to-use superconducting receivers for near and far-infrared wavelengths. In 2015, an innovative company named TIRPhotonics LLC was established within the Skolkovo Foundation. This company develops and manufactures optical integrated chips (including quantum chips) for modern scientific experiments and instruments.|
