DESCRIPTION:The second law of thermodynamics tells us which state transfor
 mations are so statistically unlikely they are effectively forbidden. It a
 pplies to systems composed of many particles and concerns average quantiti
 es. Recently\, using results from quantum information theory\, we are seei
 ng that one can make sense of thermodynamics in the regime where we only h
 ave a small number of particles\, or even a single quantum system. If we d
 on't take the thermodynamic limit\, the laws of thermodynamics are differe
 nt. The standard second law of thermodynamics still holds\, but there is a
 n entire family of second laws which also must hold.  One can also go beyo
 nd statements about average quantities and consider deterministic processe
 s or quantify fluctuations around the average value. There are also fully 
 quantum second laws which have no classical analog. After reviewing such r
 ecent results in the field of quantum thermodynamics\, the question of whe
 ther such new laws can be applied to black holes will be raised\, and rece
 nt progress in this direction discussed.
