We are developing and delivering next-generation quantum computers designed to tackle problems that are computationally intensive for classical systems-such as drug discovery, climate modeling, financial simulations, and generative AI. Our mission is to bring quantum computing into real-world applications with greater speed and precision.\nOur headquarters is located in Yokohama, while our R&D center operates within the OIST campus in Okinawa. Currently, our team consists of 3-5 members (including part-time collaborators), working closely with OIST to realize Japan's first distributed quantum computer.\nOur distributed architecture connects multiple quantum processing units (QPUs) via photonic links to form a high-performance, networked quantum system. This approach enables large-scale quantum computation that was previously impractical, opening new frontiers in quantum technology.","description_format":"text","description_chars":4234,"description_truncated":false,"requirements":{"experience_years_min":null,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":{"level":"master","optional":false},"security_clearance":false,"languages":[{"language":"English","level":"Advanced (C1)","optional":false}]},"benefits":["Insurance coverage"],"hiring_locations":[{"name":"Japan","iso":"JP","kind":"country"}],"hiring_excludes":[],"relocation_offered":false,"industries":["Quantum Science & Computing","Quantum Computing Hardware"],"lifecycle":[{"event":"open","at":"2026-10-26T09:30:52Z"}],"visa":[],"liveness":{"score":90,"band":"hot","label":"Hiring now","p_open":1,"p_active":0.896,"p_room":1,"age_days":5,"expected_fill_days":35,"reasons":["conf:1","velocity","win:early"],"computed_at":"2026-11-01T06:10:25Z"},"pay":null,"html_url":"https://alion.io/job/qubitcore-researcher-theoreticalamo","json_url":"https://alion.io/job/qubitcore-researcher-theoreticalamo.json","meta":{"generated_at":"2026-11-02T03:13:18Z","cache_seconds":300,"methodology":"https://alion.io/methodology","terms":"https://alion.io/terms","contact":"https://alion.io/contact","api":"https://alion.io/developers","about":"Alion is a live layer of people, companies and AI agents: who they are, whether they are real and active right now, what they do and how to work with them, readable by people and by agents and paid per call.","catalog":"https://alion.io/catalog.json","usage":{"tier":"crawler_verified","counted_by":"address","units_charged":1,"used_today":4843,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-11-03T00:00:00Z"}},"offers":[{"id":"company.slices","title":"One company in depth, by slice","status":"live","price":{"credits":0.02,"usd":0.002,"plus_per_slice":{"credits":0.05,"usd":0.005}},"unit":"per company, plus each slice with data","note":"the employer in depth","call":{"mcp_tool":"get_company","arguments":{"id":3716},"rest":"https://alion.io/mcp/rest/get_company?id=3716"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fqubitcore-researcher-theoreticalamo"},{"id":"market.stats","title":"A market slice: pay, demand and time to fill","status":"live","price":{"credits":1,"usd":0.1},"unit":"per slice","note":"pay, demand and time to fill for this role and place","call":{"mcp_tool":"market_stats"},"human":"https://alion.io/catalog?offer=market.stats&for=job%2Fqubitcore-researcher-theoreticalamo"},{"id":"job.search","title":"Open jobs by role, technology, place, pay and visa","status":"live","price":{"credits":0.02,"usd":0.002},"unit":"per posting in a list","note":"similar open postings","call":{"mcp_tool":"search_jobs"},"human":"https://alion.io/catalog?offer=job.search&for=job%2Fqubitcore-researcher-theoreticalamo"},{"id":"company.verify","title":"Is this company real and active right now","status":"pilot","price":null,"unit":"per company","request":{"url":"https://alion.io/catalog/request","method":"POST","body":"{\"offer\": \"company.verify\", \"for\": \"job/qubitcore-researcher-theoreticalamo\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fqubitcore-researcher-theoreticalamo"}],"agent":{"mcp":"https://alion.io/mcp/jobs","mcp_open":"https://alion.io/mcp/open","next":[{"tool":"get_job","arguments":{"id":3266473}},{"tool":"search_jobs","arguments":{"company":"qubitcore.jp","detail":"compact"}},{"tool":"match_people","arguments":{"job_id":3266473},"note":"people open to offers who fit this vacancy"}],"note":"The same data through MCP tools: https://alion.io/mcp/open needs no sign-in (compact searches, postings, people); https://alion.io/mcp with an Alion account has everything.
