Description
This project focuses on the development of methods for computing real-time dynamics of thermal states for quantum field theories on quantum devices using the 1D Ising model as a testbed. This research is motivated by the challenges faced by conventional classical methods for such systems.
We propose to prepare the thermal state on a quantum state via variational imaginary time evolution starting from a Thermofield Double state using the DualQITE approach. Subsequently, the thermal state can be evolved using standard methods and the thermal correlators can be measured over time. In the final stage, we conduct signal analysis of this data. This analysis allows us to observe the dynamics of the system and accurately measure the masses of the bound states that emerge during the evolution process.
