FEBRUARY 2025 I PCB007 MAGAZINE 107 by a steering committee to facilitate a strategic partnership among organizations interested in the total solution for interconnecting, assem- bling, packaging, mounting, and integrating system design standardization. According to an IPC paper presented at ECWC 10 at the IPC Printed Circuit Expo, as it was called at the time, JISSO is a made-up word that Japa- nese technologists created to stand for total system integration, akin to the "silicon to sys- tems" phrase that IPC uses today. e JIC and its members were committed to fostering open competition in the development of products and services based on industry needs. IPC was one of the initial JISSO organizers, along with Japan Printed Circuit Association ( JPCA), Japan Exchange and Teaching Association ( JETA), and Joint Electronic Device Engi- neering Council ( JEDEC). Denny's early work with these groups was foundational in where IPC finds itself today in developing global manufacturing standards. Denny is still involved with IPC and remains interested in and follows the industry's techno- logical advancement. Denny was considered for the Hall of Fame Award due to his involve- ment in the Assembly and Joining Committee, as well as his interest and involvement in all aspects of printed circuit board manufacturing and assembly technology. ank you, IPC Hall of Fame member Denny Fritz, for your contri- butions to IPC and the industry at large. PCB007 The number of materials that could be used in the fast quan- tum computers of the future has increased thanks to Oscar Groppfeldt's degree project, for which he had access to the university's supercomputers. It is hoped that quantum com- puters will revolutionise sev- eral different scientific fields such as pharmaceutical production, materials devel- opment and give a deeper understanding of how the laws of nature work. "If we are to be able to supplement ordinary com- puters with quantum computers in the long term, they need to work at room temperature. We are in- vestigating which materials could be suitable for this," says Rickard Armiento, researcher in theoreti- cal physics at Linköping University and examiner of Oscar Groppfeldt's master's thesis. What Oscar Groppfeldt has done in his master's thesis on the MSc programme in Applied Physics Searching for Materials for Ultra-fast Quantum Computers and Electrical Engineering (the Y programme) is to investigate which material defects could be suitable for future quantum computers. "Imagine that we have a crystal in which the atoms repeat themselves in a space, and then you remove something, like a nitrogen atom. Then what we call a defect arises that can give a lot of interesting states, which you can manipulate and get information out of. But then you need to have a defect that makes sense," says Oscar Groppfeldt. You may think that a defect indicates the material is damaged and therefore a randomness arises. But in this case, the opposite is true. What he has done is to use computer calculations to simulate the elec- trons in a variety of materials where he systematical- ly replaced and removed atoms to see which optical properties can be used for quantum bits. According to Joel Davidsson, postdoc at the De- partment of Physics, Chemistry and Biology and the- sis supervisor for Oscar Groppfeldt, the work would not have been possible just 10 to 15 years ago.
