Jij Inc. (Headquartered in Minato-ku, Tokyo; CEO: Yu Yamashiro,hereinafter "Jij") announces that Ross Grassie, who belongs to our UK subsidiary Jij Europe Ltd. and serves as our Global Technical Presales Lead, has taken on a dual role as Innovation Fellow with the University of Edinburgh’s Quantum Software Lab (hereinafter “QSL”) on 10/11/2025. In this capacity, Ross will help translate cutting‑edge research into implementable, business‑ready optimisation solutions across energy, finance and other industrial sectors.
At Jij, Ross leads technical presales engagements across the UK and Europe, shaping solution architecture and validation with enterprise partners. At QSL, he will contribute to application‑driven research, benchmarking, and skills development at the intersection of academia and industry.
Positive impact for industry and business: Closer alignment with the UK research community channels real operational needs into application‑driven research, accelerating validation on real datasets and de‑risking adoption of quantum‑classical optimisation across energy and adjacent sectors.
Positive impact for the UK ecosystem: Ross’s dual position creates a direct pathway for blue-sky research to address real operational requirements not met by current technology, opening new opportunities for quantum software to positively impact the UK economy.
