Thermodynamically optimal creation of correlations

Understand

Correlations lie at the heart of almost all scientific predictions.

• It is therefore of interest to ask whether there exist general limitations to the amount of correlations that can be created at a finite amount of invested energy.
• Within quantum thermodynamics such limitations can be derived from first principles.
• In particular, it can be shown that establishing correlations between initially uncorrelated systems in a thermal background has an energetic cost.
