The company’s unique ability to offer both hardware and software solutions, along with its commitment to build energy efficient datacenters and scalability, positions it to play a key role in the next wave of innovation, and in many strategic and sovereign industrial sectors.\nJoin Us at the Forefront of Quantum Computing Innovation\nDescription of the Team/Project\nThe Source Applications Team develops semiconductor quantum light sources and spin-photon interfaces for quantum information processing. Our work combines experimental quantum optics, coherent spin control, and photonic entanglement generation.\nPreserving spin coherence is essential for generating entangled states and performing quantum operations. This internship will investigate dynamical decoupling techniques to protect spins in semiconductor quantum dots from environmental noise and extend their coherence beyond the free-induction dephasing time, T₂*.\nWorking closely with our scientists, you will implement and compare optical spin-control sequences, identify their practical limitations, and assess their compatibility with spin-photon entanglement protocols.\nYour Key Responsibilities\nCharacterize spin coherence.\nImplement and optimize dynamical decoupling sequences, such as CPMG-family sequences.\nInvestigate how pulse timing, rotation fidelity, and excitation conditions affect coherence preservation.\nAnalyze experimental data to extract coherence times and compare the performance of different sequences.\nWork with the team to interpret results and identify the main sources of decoherence and control errors.\nDocument your findings and contribute to the development of robust spin-control protocols for quantum information experiments.\nRequirements\nEducation & Background\nCurrently pursuing a Master’s degree or a final-year engineering degree in physics, quantum technologies, photonics, or a related field.\nA solid foundation in quantum mechanics.\nPrevious laboratory experience in optics, spectroscopy, or experimental physics would be an advantage.\nTechnical Skills\nFamiliarity with quantum optics, spin physics, or coherent control.\nProgramming skills in Python or an equivalent language for data analysis and visualization.\nInterest in hands-on experimental work involving lasers, optical alignment, and measurement automation.\nExperience with pulsed experiments, cryogenic systems, or semiconductor quantum dots is welcome but not required.\nSoft Skills\nScientific curiosity and a rigorous approach to experimental work.\nPatience and persistence when troubleshooting and optimizing experiments.\nAbility to work collaboratively and communicate results clearly.\nWillingness to learn new techniques and progressively take ownership of experimental tasks.\nLanguages\nGood written and spoken English is required.\nFrench\nBenefits\nSwile Card (meal vouchers) \n50% participation in transportation costs \nPossibility of remote work \nInternship Allowance between €1,200 and €1,400 per month \n1,5 days off per month, cumulative \nWhat we also offer\nA challenging and innovative work environment at the heart of quantum computing.\nA diverse and collaborative company culture.\nOpportunities for professional growth and skill development.\nAt Quandela, we believe that the strength of our team is the plurality of experiences, perspectives, and journeys. We are committed to building a respectful, inclusive, and welcoming work environment. All applications are welcome.","description_format":"text","description_chars":3606,"description_truncated":false,"requirements":{"experience_years_min":null,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":null,"security_clearance":false,"languages":[{"language":"English","level":"All levels","optional":false}]},"benefits":[],"hiring_locations":[{"name":"France","iso":"FR","kind":"country"}],"hiring_excludes":[],"relocation_offered":false,"industries":["Quantum Science & Computing","Quantum Computing Hardware"],"lifecycle":[{"event":"open","at":"2026-11-04T15:44:26Z"}],"visa":[],"liveness":{"score":90,"band":"hot","label":"Hiring now","p_open":1,"p_active":0.903,"p_room":1,"age_days":1,"expected_fill_days":48,"reasons":["conf:3","velocity","win:early","comp:junior"],"computed_at":"2026-11-06T05:58:05Z"},"pay":{"stated_usd_annual":18816,"is_top_pay":false},"html_url":"https://alion.io/job/quandela-source-application-intern-h12027","json_url":"https://alion.io/job/quandela-source-application-intern-h12027.json","meta":{"generated_at":"2026-11-06T07:41:57Z","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":13705,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-11-07T00:00:00Z"}},"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":704},"rest":"https://alion.io/mcp/rest/get_company?id=704"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fquandela-source-application-intern-h12027"},{"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%2Fquandela-source-application-intern-h12027"},{"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%2Fquandela-source-application-intern-h12027"},{"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/quandela-source-application-intern-h12027\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fquandela-source-application-intern-h12027"}],"agent":{"mcp":"https://alion.io/mcp/jobs","mcp_open":"https://alion.io/mcp/open","next":[{"tool":"get_job","arguments":{"id":3752340}},{"tool":"search_jobs","arguments":{"company":"quandela.com","detail":"compact"}},{"tool":"match_people","arguments":{"job_id":3752340},"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.
