Quantum Many-Body Theory, Quantum Information Theory, and Quantum Optics Research Group

Role in the consortium

This theoretical project supports experimental efforts in a number of ways. It sets out to develop protocols for certifying the functioning of schemes, including notions of Hamiltonian learning. It contributes ideas of quantum error mitigation and correction. It contributes to identifying optimal protocols. Finally, it assesses the potential for reaching a quantum advantage with cold atomic platforms.

What are the goals?

  • A goal is to develop tools for certifying the correctness of quantum simulations by means of analog randomized benchmarking and Hamiltonian and Liouvillian learning.
  • A complementing goal is to develop new protocols for physics non-agnostic quantum error correction tailored to the physical system at hand.
  • An overarching goal is to see how and in what sense quantum advantages can possibly be achieved.

How do we plan to achieve that?

We plan to achieve these goals by bringing together a portfolio of the theory and quantum optics of cold atomic quantum gases, of quantum systems identification, of signal processing, machine learning, complexity theory and the theory of quantum error correction.

FUB partner brings in expertise in the study of cold atomic quantum many-body systems and of notions of quantum computing. Specifically important for the project is our strong background in notions of quantum systems identification, benchmarking and certification on the one hand and of quantum error mitigation and correction on the other. Expertise in protocol design is also relevant for the project when it comes to developing new schemes for quantum computing. The group often brings in highly conceptual work. At the same time, the team has a long-standing track record of successfully working and publishing with leading experimental groups.
