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.

Temperature of the three-state quantum walk.
Despite the coined quantum walk being a closed quantum system under a unitary evolution, its Hilbert space can be divided in two sub-spaces, which makes it possible for one to analyze one of the
Temperature and entanglement of the three-state quantum walk
In the present work, the evolution of a three state quantum walk without decoherence is investigated. Despite being a closed quantum system under unitary evolution, its Hilbert space can be divided
