Entropy and temperature of a quantum Carnot engine
... In the analysis above we have considered only the square-well potential model, which can be interpreted as the quantum analogue of the classical ideal gas. A natural extension of this work would be to consider other Hamiltonians. For example, for a harmonic potential whose energy eigenvalues are En ...

Rule 1 (State Description) N states, probability vector Rule 2 (Evolution) N x N stochastic matrix Rule 3 (Measurement) A measurement with k outcomes is described by k N dimensional real vectors with positive components. If we sum over all of these k vectors then we obtain the all 1’s vector. If our ...

The meaning of time evolution is also nonvanishing and has an interpretable notion in the microscopic world of quantum mechanics. It is precisely the reason why classical and quantum computations are evolved by a sequence of time ste ...
