Ground State Preparation via Dynamical Cooling

Understand

Quantum algorithms for probing ground-state properties of quantum systems require good initial states.

• Projection-based methods such as eigenvalue filtering rely on inputs that have a significant overlap with the low-energy subspace, which can be challenging for large, strongly-correlated systems.
• This issue has motivated the study of physically-inspired dynamical approaches such as thermodynamic cooling.
• In this work, we introduce a ground-state preparation algorithm based on the simulation of quantum dynamics.
