量子コンピュータ理論サイエンティスト (13738)
職種Position R&D / Engineer /Technician (Mechanical, Electronics)
会社概要Company profile This is with a deep-tech startup developing and commercializing world-leading neutral-atom quantum computing systems, one of the most promising next-generation computing architectures.

The company was established in collaboration with leading quantum physics research groups in Japan and is working toward the practical realization of quantum computers as a next-generation computational platform. Through joint research initiatives with universities, national laboratories, and global technology partners, the team is advancing quantum hardware development for future industrial applications and international markets.

Quantum computing is expected to transform industries such as:

drug discovery
advanced materials design
artificial intelligence
financial optimization
energy systems

Among multiple quantum architectures, the company focuses on neutral-atom quantum computing, widely considered one of the most scalable and promising approaches for large-scale quantum processors.

This role offers a rare opportunity to contribute not only to research infrastructure but also to the real-world deployment and industrialization of next-generation computing technology.
仕事内容Job description Here is a professional, research-grade English version suitable for a theoretical quantum scientist / quantum algorithm researcher job description. I adjusted phrasing to match how deep-tech / quantum hardware startups (e.g., Pasqal, QuEra, PsiQuantum) describe theory roles.

1. Mission (Purpose of the Role)
Through research in the fundamental theory and mathematical foundations of quantum computing, this role contributes to building the theoretical basis that will serve as a long-term source of technological advantage and future commercialization.
This position is not limited to short-term product implementation. Instead, it plays a central role in supporting the company’s mid- to long-term competitive edge, intellectual property strategy, and research narrative as a core member of the theoretical research team.

2. Key Responsibilities
(1) Quantum Computing Theory and Mathematical Research
Conduct theoretical research on quantum computation models, including:
• gate-based quantum computing
• analog quantum computing
Investigate topics such as:
• quantum algorithms
• quantum error correction
• quantum complexity theory
Develop and validate mathematical and physical models supporting quantum system design and computation
________________________________________
(2) Translating Research Outcomes into Business-Relevant Directions
Structure and formulate hypotheses that connect theoretical research outcomes to business themes and practical use cases
Collaborate with implementation teams including:
• quantum engineers
• software engineers
• hardware engineers
to align theoretical insights with system requirements
Contribute to the development of technology roadmaps by identifying theoretical limits, opportunities, and strategic directions

(3) Research & Intellectual Property Activities
Publish research papers and present results at international conferences and workshops
Organize theoretical ideas for patent development and invention extraction
Lead theoretical components of joint research projects with:
• universities
• research institutes
• industry partners

(4) Internal and External Communication
Provide technical explanations to executives and investors, including non-specialist audiences
Articulate the significance and long-term impact of research themes
Contribute to building and sharing theoretical knowledge within the organization and supporting the development of an internal research culture
