 periments on superconducting nano-circuits\, which test the role of inform
 ation in thermodynamics. Two types of Maxwell's demons (MD)\, a Szilard’
 s Engine and an autonomous MD\, were realized based on single electrons. I
 deally they extract heat and do work equal to kT log(2) per operation cycl
 e\, in accordance with the Landauer principle for the cost of erasing a si
 ngle bit in computation. In our experiments we achieve 75% of this bound p
 er cycle\, and the missing efficiency can be quantitatively accounted for 
 by assigning the entropy of mutual information\, due to incomplete measure
 ment\, on the same footing as other contributions of entropy. In the secon
 d part of the talk I present quantum heat engine (refrigerator) based on a
  superconducting qubit.
