Synthetic Quantum Systems Theory

Our research mission is to achieve a deeper understanding and precise control of synthetic quantum systems.

Supported by the ERC Starting Grant StrEnQTh — Strong Entanglement in Quantum many-body Theory

# Research

Our research is geared towards leveraging the potentials of synthetic quantum systems with the aim of developing novel quantum technologies such as quantum simulation, quantum computation, and quantum metrology.

We perform theoretical studies based on analytical and numerical methods, as well as develop proposals for realizing and characterizing phase diagrams and non-equilibrium dynamics of quantum many-body systems.

These proposals draw on the astonishing abilities of quantum devices, e.g., based on ultracold quantum gases, trapped ions, or superconducting qubits, which are now reaching a level of precision and control that has been unimaginable just a few decades ago.
