Abstract
A general expression for the temperature of a finite-dimensional quantum system is deduced from thermodynamic arguments. At equilibrium, this magnitude coincides with the standard thermodynamic temperature. Furthermore, it is well-defined even far from equilibrium. Explicit formulas for the temperature of two and three-dimensional quantum systems are presented, and some additional relevant aspects of this quantity are discussed.
