A mechanical-piston Szilard engine driven by a run-and-tumble particle can extract positive work despite measurement errors, with an information efficiency that can nominally exceed Landauer's bound and that improves under cyclic operation.

Mechanical work extraction from an error-prone active dynamic Szilard engine
A mechanical-piston Szilard engine driven by a run-and-tumble particle can extract positive work despite measurement errors, with an information efficiency that can nominally exceed Landauer's bound and that improves under cyclic operation.
