The successful candidate will be joining the Macroscopic Quantum Optics Theory group led by Prof. Dr. Oriol Romero-Isart.\nOur PhD-program brings together top-level training and teaching for young scientists, benefiting from the extensive course offerings of local universities and focused instruction by ICFO professors, in a stimulating, international and interdisciplinary environment. PhD-students have the opportunity to take advantage of our network of excellence, consisting in partners of national and international research institutes and universities, as well as industrial partners in the field.\nThe successful candidate will join a research project funded by a “la Caixa” Junior Leader Fellowship at ICFO. The project, “Tabletop Tests of Fundamental Physics with Levitated Nanoparticles,” will be carried out within the Macroscopic Quantum Optics Theory group Macroscopic Quantum Optics Theory group led by Prof. Dr. Oriol Romero Isart and aims to explore how levitated quantum optomechanical systems can be used to investigate fundamental questions in physics, including the search for new fundamental interactions, dark matter, and signatures of the quantum nature of gravity.\nMain Tasks and Responsibilities\nThe candidate will conduct theoretical research at the intersection of quantum optics, quantum information, and fundamental physics. Their work will involve developing analytical and numerical tools to model quantum systems and designing experimentally feasible protocols for precision sensing and tests of fundamental physics.","description_format":"text","description_chars":1768,"description_truncated":false,"requirements":{"experience_years_min":null,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":{"level":"phd","optional":true},"security_clearance":false,"languages":[]},"benefits":[],"hiring_locations":[],"hiring_excludes":[],"relocation_offered":false,"industries":["Quantum Science & Computing","Hydrogen Energy","Quantum Computing Hardware"],"lifecycle":[{"event":"open","at":"2026-10-26T14:02:09Z"}],"visa":[],"liveness":{"score":83,"band":"hot","label":"Hiring now","p_open":1,"p_active":0.825,"p_room":1,"age_days":8,"expected_fill_days":25,"reasons":["conf:3","win:early"],"computed_at":"2026-11-04T06:34:25Z"},"pay":null,"html_url":"https://alion.io/job/icfo-phd-position-in-macroscopic-quantum-optics-theory","json_url":"https://alion.io/job/icfo-phd-position-in-macroscopic-quantum-optics-theory.json","meta":{"generated_at":"2026-11-05T02:22:16Z","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":3077,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-11-06T00:00:00Z"}},"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":1770496},"rest":"https://alion.io/mcp/rest/get_company?id=1770496"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Ficfo-phd-position-in-macroscopic-quantum-optics-theory"},{"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%2Ficfo-phd-position-in-macroscopic-quantum-optics-theory"},{"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%2Ficfo-phd-position-in-macroscopic-quantum-optics-theory"},{"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/icfo-phd-position-in-macroscopic-quantum-optics-theory\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Ficfo-phd-position-in-macroscopic-quantum-optics-theory"}],"agent":{"mcp":"https://alion.io/mcp/jobs","mcp_open":"https://alion.io/mcp/open","next":[{"tool":"get_job","arguments":{"id":3275078}},{"tool":"search_jobs","arguments":{"company":"icfo.eu","detail":"compact"}},{"tool":"match_people","arguments":{"job_id":3275078},"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.
