# Research

#### Quantum Simulation

Solving quantum many-body problems beyond the limits of classical computers using quantum devices

Shedding light on hidden properties of quantum many-body systems

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.
