The floating block method pictured as ice blocks and the sea. The method applies a filtering process called imaginary time evolution to two Hamiltonians, represented by ice and sea. It gives the overlap between the two Hamiltonians’ lowest energy states.

Computing How Quantum States Overlap

The floating block method provides the tools to compute how quantum states overlap and how to build fast and accurate emulators of those systems.
