We partner with global leaders in government, academia, and the private sector to identify applications that would benefit from quantum-based applications to current and future commercial challenges. We engage with customers early and throughout the development process to improve market fit.

Our team’s unique approach enables cross-pollination across a diverse range of fields, from physics, computer science, neuroscience, mathematics, cryptography, natural sciences and more! Our success comes from coalescing diverse talent to create an environment where experimental thinking and collaboration yield breakthrough AI + Quantum solutions. Join a culture where thought leadership, diverse talent, employee engagement, and technological impact will create the next tech uproar.

We are deeply committed to education as a means to advance quantum solutions and computing initiatives. We invest in future talent through internship programs, research papers, developer tools, textbooks, educational talks/events and partnerships with universities/talent hubs to attract multi-disciplinary talent. Our hope is to inspire people from all walks of life to be prepared for the quantum era and encourage a path in STEM.

Tensor Networks Postdoc

Our S&O team is looking for applicants for a post-doc position in tensor network simulations. We are looking for highly motivated candidates with deep expertise in numerical tensor network simulations, quantum many-body theory and linear algebra to help us develop next-generation tools to solve hard computational problems for industrial applications. We are specifically interested in candidates with expert knowledge of DMRG, PEPS, TTN and related techniques. Additional background in computational quantum chemistry, financial modeling, machine learning, HPC or any other quantitative field is highly welcome.

Minimum Qualifications

  • PhD in Physics, Mathematics, Chemistry, Computer Science or related quantitative field
  • Deep familiarity with tensor networks, i.e. matrix product states, density matrix renormalization group, projected entangled pair states a.s.o.
  • Highly impactful scientific track record, as demonstrated by academic publications and/or conference presentations
  • Ability to operate independently on a research agenda, willingness to take ownership of projects, and ability to drive projects forward and bring them to conclusion
  • Proficiency in Python, including the usual python stack for scientific computing (numpy, scipy, jupyter, a.s.o.)
  • Familiarity with Linux 

Preferred Qualifications

  • Familiarity leveraging GPUs or other accelerators for scientific computation
  • Experience with JAX, tensorflow or pytorch
  • Experience with machine learning
  • Experience with electronic structure calculations (Hartree-Fock, Density Functional Theory)
  • Experience with electronic correlation methods for quantum chemistry (full CI, coupled cluster, perturbation theory, CAS-SCF, a.s.o)
  • Experience with cloud computing

Core responsibilities

  • Perform cutting edge research into applications of tensor network methods to industrially relevant problems
  • Perform feasibility studies of tensor network methods to solve relevant computational problems
  • Implementation of prototype solutions, including code development, running simulations, gathering data and data analysis.
  • Presentation of results at internal meetings as well as external conferences
  • Documentation of work in form of internal documents as well as publications in academic journals

Duration: 1 year fixed term, with the possibility for renewal for one additional year after the first year.

What to Expect:

  • Work on challenging technical projects with scientists and engineers
  • Opportunity to interact with with a multidisciplinary team across the whole company
  • Competitive compensation
  • Presentation of findings to the rest of Sandbox AQ
  • Have fun!
