Postdoctoral Research Fellow in Quantum Machine Learning for Multimode Mechanics

A three-year position as Postdoctoral Research Fellow inQuantum Machine Learning for Multimode Mechanics (QM3L / QuantERA 2025) is available at the Department of Physics.

Supervisors are Prof. Francesco Massel and Prof. Morten Hjorth-Jensen.

Starting date no later than January 1 2027.

No one can be appointed for more than one Postdoctoral Research Fellowship at the University of Oslo.

The postdoctoral position is part of the QuantERA project QM3L - Quantum protocols for Multimode Mechanics advanced by Machine Learning a European consortium combining theory algorithms and experiments on multimode mechanical quantum platforms (circuit quantum acoustodynamics with transmonHBAR devices; HBAR arrays; microwave optomechanics).

The postdoc will work at UiO with Massel and Hjorth-Jensen focusing on theoretical and algorithmic developments that enable machine-learning-assisted discovery control and certification of complex multimode quantum states. The work will interface closely with experimental partners (ETH Zürich Aalto University) and theory partners (TU Darmstadt Palacký University).

Main work tasks may include (depending on profile and project needs):

• Develop ML-assisted Hamiltonian discovery/engineering methods for multimode bosonic and hybrid quantum systems (including open-system and non-Hermitian effects).
• Design noise-resilient control and optimization strategies including reinforcement learning (RL) and optimal control approaches for state preparation and measurement protocol design under hardware constraints.
• Develop open-source software and documented benchmarks.
• Co-author high-quality publications and contribute to consortium deliverables and reporting; participate in partner visits workshops and training activities.

The main purpose of a postdoctoral fellowship is to provide the candidates with enhanced skills to pursue a scientific top position within or beyond academia. To promote a strategic career path all postdoctoral research fellows are required to submit aprofessional development plan no later than one month after commencement of the postdoctoral period.

The Faculty of Mathematics and Natural Sciences has a strategic ambition to be among Europes leading communities for research education and innovation. Candidates for these fellowships will be selected in accordance with this and expected to be in the upper segment of their class with respect to academic credentials.

Required qualifications:

• A degree equivalent to a Norwegian doctoral degree inphysics applied mathematics computer science or a closely related the degree is not yet formally received the doctoral dissertation must be submitted for evaluation by the application date. Only applicants with an approved doctoral thesis and public defence are eligible for appointment.
• Strong background in at least two of the following:
  • quantum optics / quantum information / open quantum systems
  • quantum control / optimal control
  • machine learning (including deep learning and/or reinforcement learning)
  • numerical simulation of quantum dynamics
• Proven programming skills (e.g. Python/Julia/C) including experience with scientific computing tools
• Ability to communicate research results clearly in written and oral English

Desired qualifications:

• Experience with reinforcement learning for physical control problems and/or sample-efficient optimization
• Familiarity with continuous-variable/bosonic systems non-Gaussian states multimode entanglement or Wigner-function methods
• Experience with HPC workflows (cluster computing GPU computing reproducible pipelines)
• Track record of collaborative work across theory/experiment or interdisciplinary teams

All candidates and projects will have to undergo a check versus national export sanctions and security regulations. Candidates may be excluded based on these checks. Primary checkpoints are the Export Control regulation the Sanctions regulation and the national security regulation.

Personal skills:

• Strong collaboration skills and willingness to work in an international consortium with frequent interactions across sites and disciplines
• Ability to mentor students (informally or formally) and contribute to an inclusive working environment

Employment in the position is based on a comprehensive assessment of all qualification requirements applicable to the position including personal skills.

• Exciting and meaningful tasks in an organization with an important societal mission contributing to knowledge development education and enlightenment that promote sustainable fair and knowledge-based societal development
• Committed colleagues in a good working environment
• Good welfare schemes.
• Opportunity of up to 1.5 hours a week of exercise during working hours.
• A workplace with good development and career opportunities
• Postdoctoral development programmes.
• Membership in the Statens Pensjonskasse which is one of Norways best pension schemes with beneficial mortgages and good insurance schemes
• Salary in position as Postdoctoral Fellow position code 1352 in salary range NOK 595 000 - 690 000 depending on competence and experience. From the salary 2 percent is deducted in statutory contributions to the State Pension Fund
